Someone help me to make sense of this?

I don’t know what is wrong with me. Some people may call it laziness. But I don’t think that is what it is. I’ve been spending whole days at home, refusing to go out or talk to anyone. I read it online that I may be avoiding reality because there is something in my mind that it hurts too much to think about. Well, there is. It is about a person. And I don’t feel the same way about that person that I used to anymore. Instead, I feel disappointed. And really angry at myself sometimes, although I don’t know why. I just want this feeling to go away. Because, whenever I get close to someone to get a little bit of comfort, they turn their backs on me and walk away. What is it about me? I would like to believe that I put my trust on the wrong sort of people. But what if it is me? Am I chasing people away? Can I actually trust anyone??
