I really wish I knew what is wrong with me. I constantly feel as though something is amiss in my relationship. It makes my stomach churn and at random times I just feel like crying. I don't know why. It's like there's something eating away at me and I just can't put my finger on it. Sometimes, Melissa will look at me and ask me what's wrong, and I tell her "nothing." It's not really nothing, it's something - but i don't know what. I don't know what to tell her. I know it may look like I'm hiding something, but I'm not. I just don't know what it is. I don't know why I feel like this. I've tried really hard just to ignore this feeling. I just want it to go away and things to go back like they were before. I don't want to feel so insecure. I don't want to constantly feel the need to apologize when I haven't done anything. Why can't I get my head straight?
