Sorrel, the quote by Jung is right... though I don't agree with his stuff all the time...

((((WI)))))) maybe you can try thinking, instead of "I Can't", that "I don't want to" or "I'm not sure I can?" It may sound trivial but it will help to reduce some of the agony you are going through... and you can do this... you can... you can... but I'm sorry it's such a tough time for you.
