Yep, i can definitely understand what you're feeling. I often think the same thing about myself. I feel worthless most of the time. I don't really know how my boyfriend can love me. I know i don't treat him very well when i'm depressed. Yet, he still puts up with it. I have went through and seen so much negativity in my life that it's like i expect everything to be negative now. It's just such a difficult thing that weighs me down. :-( Nobody should have to go through this. Hope you feel better soon! Apparently, we are loved and we do deserve happiness so we should just be happy.
