Why do I feel bad whenever someone asks me to do them a favour?

[Timerk]

I enjoy doing things for people, but when people take advantage, I don't feel bad as much as I feel angry.

I am the opposite; I feel sad and hurt more than anything else.

When someone does that to me, it also makes me feel really alone. It makes me think there is something wrong with me...I know that it isn't right to feel that way, but I can't help it.
