Am I too old for college life?

Ok just to make it short Im 20 about to be 21 in 23 days (woo.hoo) and i really want to go to school. I went to community college right after i graduated in 06 and my bro died in iraq so i dropped out. Right now i work full time and have my own apartment. Im really starting to hate my apartmnt its lonely and i work too much to try to keep it clean. and i couldnt see myself goin to school and working full time and trying to keep up with all these bills. My question is am i too old to go live in a dorm? did my chance already p me for the whole college expeirence? how old do you think is too old to live in the dorms?
