Too Good

Why can't I seem to stop from doing extra things for ungrateful people. When actually everything is for naught. I always felt guilty like I have to pay some kind of debt. I can't stop thinking that I must do something to make those near me happy. And those people have done nothing for me. All they did was take me for granted and made me feel like a worthless person. I'm not even sure if my college friends are true and real. If they can be there for me when I needed it just like how I was for them.
