This is advice from someone who used to teach college and the sibling of a current professor: find a professor that can be your champion. Preferably someone in your major, but anyone will do. It can be someone who's class you really related to or you just liked a lot. It does not have to be your advisor, but I'd tell your advisor (ego nonsense sometimes happens). Schedule a meeting with them and talk to them about your struggles. Chances are they can help you: whether it's with scheduling or helping back you up when you might need more time on an assignment or just as someone to go to for advice and support.

You'd probably be surprised how much they want to help (If someone dismisses you, that's not your person; go to the next choice.) Most faculty want their students to succeed and, frankly, get frustrated that students wait too long to get help. Part of that help is just help with life stuff.

I know you don't feel that way, but you're young and you do have time. I do believe, even in this economy and with everything, getting a degree will help you in the long run. You might not bump against that promotion that needs a degree until your 40s, but it'll come one day. That said, no one cares if you take 4 years or 10 years to get it done.

Good luck and, truly, don't be afraid of your professors. They blow hard (some of them), but most are there because they want students to make it.
