Sounds like you are in a tough spot right now. I wouldn't recommend taking time off school, but that's just my opinion. I think that it's harder to get back in once you get out. Especially because from what I got from your post is that you really aren't that motivated to go to college in the first place. Friends are hard to come by. I didn't have any for awhile and then I had bad ones and then I had none again and now I have great ones. I had aquaintances in college and then at various jobs. We rarely got together outside of school or work, but we were close when we were together. Situational friends I suppose.
Anyway, sounds like you need to take stock...figure out what is important to you and what your goals are. If you have no goals, figure out what would be smart to do and what could hurt you down the road. Ask others for advice, not just us, and listen to it, even if you disagree. Everyone has at least one good thing to say...sometimes it's just buried in shit.
