Thanks to everyone who replied.

It's not that don't trust anyone. Rather, my parents tell me I trust too easily.

I don't hide my problems from others to protect myself from them. It's so that I don't have to listen to myself say things I don't want to hear about myself.

I know people genuinely want to help me.

I think I unintentionally hurt others by invalidating their concern for me.

My sister got really frustrated with me for telling her to leave me alone.

There was also one night I was drunk and crying with one of my co-workers. Despite my display of emotion, I still had my walls up. I felt bad when I kept refusing my co-worker's offer to listen to what was wrong.

My parents tell me I need to be more open with them too.

It makes me sad.

I don't say things unless people pry.

I can't expect everyone to keep caring if I push them away.

I hate myself.
