I completely agree with the others: I live for my family and my friends. Its also true that simple things are the most important: getting up in the morning and seeing Anita, or just talking with my friends.
It could also be good if you know that you are making someone happy. Im sure that your family needs you, and this only thing is a reason for living. I also agree with the others, you could find some volunteer work, it might help you to feel better...

Hugs for you
