I'm sorry you are having such a difficult time especially at such a young age. (By the way... you mentioned imagining, when you're 80, you'll be just another brick in the wall. Well... I'm 71! And, yes, I guess I'm just another brick in the wall. But I have to say, once you get there, being just another brick in the wall has its benefits.
