I'm so useless.

Sometimes. I really wonder. Why am I doing so much for my friends, taking time and effort just to make each and everyone of them feel special and loved, make them feel that they're important to me. It seems like they just take it for granted. When I'm here giving my 100%, they probably only give 70%.Let they're telling me that I'm not as important as how they are important to me. If so, then why am I working so hard, bothering about whether they know that they're this important to me? When I try so hard to make you feel special, you disappoint me.
It's really discouraging.
