Used much?

Do you ever feel used by people who claim they are your friends and claim they like you? Yeah ... I do. Practically every day. It gets really old. I'm totally fine being a good friend and being there for people but for them to take advantage of my kindness is really wearing me down. I wish they would just realize that I have feelings and I'm not just here for them to use me and abuse me. Please...stop. Just be my friend and not use me. I would really appreciate it...
