It really depends what you want to do - do you need a college degree for that? If so, do you think you would be able to manage the workload?

I went through a stage when I first started uni where I was similar - depression sank in and I didn't go to classes, did bare minimum and my grades and GPA suffered. I ended up leaving. A few years later I tried again and things were different. My mind was in a different place where I could keep up with the demands. It wasn't always easy but it was possible.

For me, the deciding factor was that I needed a university degree for the job I wanted to do. I spent a year just working and found that I wasn't happy. It gave me some of the motivation to go back and try again.
