Your case sounds psychological rather than physiological :/ Remember that it is your nervous system that is triggering those physiological responses (fatigue, anxiety etc...) from the information in your environment that your brain process. My advice is cognitive-behavioral therapy or biofeedback.

This nutrient has been called the anti-stress vitamin:

h**p://en.wikipedia.org/wiki/Pantothenic_acid

Roger Williams discovered it, and Linus Pauling advocated it's use    It's essential to many biological processes    It's not as easily available as other essential nutrients, which is undoubtedly due to lack of information being published by agencies as to it's value  An article from Ames concerning it is attached 

Stress, by definition, cannot be overcome. While trying you are swimming upstream on a neverending river. It works out best to let yourself relax and not accept all the opportunities in front of you. Stress will eat you alive and since you get washed out to sea in the end anyway it makes sense to thread water sometimes and go with the flow at others.

music is very powerful. 

Look over what you were writing earlier and question everything.  Whenever you hear the words inside "I have to" stop and question your beliefs and see what is driving you.

I spent a over a year once a week with a great psychologist who said "the ONLY valid reason to do anything is because you WANT to".  It took me another year to really understand those words.  The only exception to that is things you TRULY need to do to survive.

I also know first hand that some activities "feeds you".   Meaning it feels effortless and you wind up with more energy afterwards.   

Sometimes your mental state while you are doing something can make a fun task draining, for example if you have critical voices in your head while you're doing something.  It's like the thing they call "chi".

 Very often, voices that say you "Must do"  are operating from fear based motivations.  Fear based motivations are derived from outdated programs from early childhood which said "I must please/attach to those around me in order to survive".  When you are adult this need to be attached is no longer vital to your survival but you still believe it is. 

It's like a program in your startup folder on your PC that runs when you boot without you asking it to.  You may not be aware you don't have to run it anymore. 

Most people run all sorts of programs without knowing what or why they are doing things.  When guru's talk about the "conditioned mind" this is what they are talking about.  It's like when you learn to do something by repeating it like driving a car or riding a bike - your autonomic system takes over so you don't have to think about the individual actions required to perform these functions.   You've written a macro for it.

Most people live their day to day life out of these autonomic processes with very little thinking or direction taking place.  Which is why marketing is such big bucks and people are so easy to manipulate (program).  No one sitting at the desk moving the mouse makes for a machine you can easily control.

When we judge our experiences we are doing so out of a need of our Autonomic system - it wants to know is this something to avoid - a hungry predator, or is it something it wants to attach to such as food, shelter etc.  So the judging of experience is part of that feedback loop that programs our own behaviors.  If you had a negative experience in one of the tasks you think you need to perform you will start to avoid it automatically - making a negative energy loop for that task.

And while all of this appears somewhat psychological it is part of a physical loop - I think what they call the subconscious mind is really the ANS and its survival programs doing it's thing to keep us alive.  The physical loop is part of what causes type-2 diabetes and a whole host of other stress related illnesses.

There's a fascinating book called "Why zebras don't get ulcers" that covers a lot of the details.   I'll pm you a copy if you can't find it.  Also attached a book about marketing and science called "Trust us, we're the experts".

"While my guitar gently Weeps" would be appropriate at this point.

No one alerted you.....

How about adaptogens. Such as ginseng (there are a couple of different, unrelated adaptogenic plants going by the name ginseng), Rhodiola rosea, etc.

Adaptogens help regulate the hypothalamic-pituitary-adrenal axis, boosting glucocorticoid levels if they are too low and lowering them if they are too high, helping one to better cope with stress.

Or go for a nice long hike out in the woods, hitting a bar on the way home for dinner and a pint or three.

Classical music does wonders for me. Especially the composers from the romantic era, Liszt, Grieg, Rimsky-Korsakoff...

IME the most effective stress reliever is daily meditation.  Nothing major, just 10 - 30 minutes a day. Being able to shut up internally and exist in the now is a wonderful feeling. One of the most effective meditations I found was to remind myself immediately upon waking how much I have to be grateful for, and that it is all impermanent. Spending even 5-10 minuites meditating on the the phrases "my death is certain", "my time of death is uncertain", and "what will matter when I die" really put things into perspective for me with regards to stress.

(these are all buddhist meditations, but the techniques can be applied secularly with spectacular results)

I have way more links if anyone is interested.

Clyde: I am interested in the different schools/methods of meditation, PM me the links if they wont fit here.

Ok, I'll just pool all the links I can remember here then.

hxxp://diydharma.org/ -- My first resource on the topic, and possibly my favorite overall. They host a great deal of lectures and Dharma talks by Buddhist teachers. If your looking for meditations then the Guided Meditations section is where you will want to go. I really recommend looking into the lectures as well, especially if you have an interest in cognitive behavioral therapy / philosophy etc.

hxxp://www.audiodharma.org/ -- Similar to diydharma this site houses audio talks from the Insight Meditation Center in California.

hxxp://www.insightmeditationcenter.org/books-articles/meditation-instruction/ -- Meditation Instructions.

hxxp://www.vipassanadhura.com/whatis.htm -- An introduction to vipassana (insight) meditation.

hxxp://www.vipassanadhura.com/howto.htm -- A simple and effective guide to vipassana meditation.

hxxp://www.audiodharma.org/series/1/talk/2418/ -- A 4 talk long series on metta (loving kindness) meditation. Worthwhile imo.

hxxp://againstthestream.org/ -- Punk-rock Buddhism. Very interesting fusion.

hxxp://www.thegreatcourses.com/tgc/courses/course_detail.aspx?cid=687 -- If your really interested this audio course is a great introduction to the schools of Buddhism, history of Buddhism, etc

A few notable talks that I think people here would enjoy:

Dr. Gabor Mate -- Taming the Hungry Ghost:  A Biopsychosocial View of Addiction

Death meditation is intense. For about 2-3 weeks I woke up every morning and after rolling out of bed I would spend 20-30 minuites meditating on the mantras "My death is certain.", "My time of death is uncertain.", "What will matter when I die?", and "This is my last day to live."

Really puts the rest of the day into perspective... I wasted less time, and had more meaningful experiences.
