College has been a nemesis for me too. I had to take incompletes on 4 classes because I was dealing with insomnia, depression, and a reading disorder. Took me 6 months of vision therapy to get my eyes sorted out and to finish those classes. I felt like a total failure too. But it wasn't over after that. That was my first college. I am now on my 4th and still no degree. I have enough units technically to be a bachelor's graduate, but my classes are in so many varying fields that they don't add up, plus they say my 2 years at the 1st college is not accredited by some insititution they will recognize. So here at college #4 I am a sophomore and in need of vision therapy again, still dealing with depression, sleep issues, and no sign of graduating ever in sight as I only take 6-8 units per quarter and even that stresses me out. I'm a perfectionist, as if I didn't already have enough problems and have just been diagnosed with bipolar. I hope all this doesn't make you feel worse because that was not my goal. I'm just saying that you're not alone in struggling with school, but don't give up on yourself. Perhaps taking one or two less classes and focusing on them, getting a tutor, and finding out if you have some type of learning disability and getting it documented with your school will ease some of your problems. I finally gave in and got mine documented just at the end of this last quarter and I've been in college for 10 years off and on now! Take care of yourself and definitely ask for help from your school, therapist, someone you can trust, etc.
