How do I detach from someone I "don't like" - on another forum, not Psych central.

They message me about 15 times every day. I usually take days to reply but I think they want me to rescue them. I can't really do that. I do care about them though. Am I a mean terrible person who should be punished all my life?

How do I protect my boundaries without being cruel. I don't want to hurt them. Nobody on pc.

Thanks for being here
