nice guys finish last

I've finally gotten tired of being nice all the time. I'm tired of keeping quiet when somone pisses me off. My roommate scolded me beacuase I accidently put the heat on instead of turning the air off. It is always to fucking cold in our place. I never complain. I just put up with it. I go to sleep at night and if I only have one blanket I freeze my ass off. but I don't complain. I know I'm just resentful but I can't help myself. I have been having a rough time lately. I called three people that I knew on wednesday and left messages that i wanted to talk to them. I never heard from any of them. I talked to my friend yesterday about some things that were bothering me and he didn't or maybe couldn't help. I spend a lot of time helping others and have a very hard time asking for help. It seems that when I do need help I can't get it or no one understands. My sponsor said he never suffered from depression so he can't help. he doesn't know what to say. i understand that but i'm not too sure what to do to feel better. It seems i put a lot of effort into it and don't get enough back. or maybe my expectations are too high. don't know. not sure i care.
