"A human being is part of a whole, called by us the Universe, a part limited in time and space. He experiences himself, his thoughts and feelings, as something separated from the rest--a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty."
-Albert Einstein

Perhaps it's not the best quote for this situation. However, if nothing else it shows that even people we think of as almost "inhuman" had problems in their lives.

One that helps me alot whenever I'm feeling that way is this...

"The best cure for worry, depression, melancholy, brooding, is to go deliberately forth and try to lift with one's sympathy the gloom of somebody else."
- Arnold Bennett

I don't know if anything I write will help keep you from falling apart too badly... but I hope that you don't feel so alone.
