Well I had this problem for a long time. I have these periods where I get very very sad. I start crying and thoughts come to mind such as does anybody care about me, I'm worthless, there I go again crying....and everybody hates me. I tried doing research and so far it looks like I might be suffering from depression. I started reading a book that talks about how to raise yourself esteem and it helped some. I learned that depression sometimes starts with having very low esteem. I am know for certain that I do have low self-esteem. I tried to think positivly and try to be more upbeat but it always seems like I fall right back down to my little puddle of tears. Is it because I am not trying hard enough to change? Or is it something else.
