You're not a failure. You're doing something that's very difficult. I returned to college in my late 20's after a 6.5 year break and having worked fulltime in a "real" job. It was sooooo hard to do school fulltime after so long. Hard to give up the comforts of having a decent-paying, solid job. So I cna relate. I worked part-time; sounds like you are, too. That's a lot to do; school itself can be a lot. On top of that and you're dealing with mental health problems. Wow. Major burden. School is a constant, recurring test (no pun intended) of self-esteem. I felt in doubt everyday about whether i could handle the stress. You should be feeling stressed right now, i.e. that's NORMAL for what you're doing. You need to handle the pressure, relieve the ongoing attacks on your self-worth; being "tested" all the time is a challenge where you're asked to prove your (academic) worth.

I can't offer helpful advice but to say: You're not crazy for feeling so much pressure. Your response is normal.

Took me 12 years to get my BA--did it in 2 major chunks, but still it was 12 years. I didn't think I'd make but I did. Worried at every point about whether or not I could continue. At the end, I started working full-time again and went to school part-time. Going to school part-time isn't a bad idea sometimes; whatever works. If it's what you need, do it. It doesn't mean you're a failure.

You can do it.
