With me lack of motivation is part of my depression. I'm in college too and working on my bachelors and then I want to take it further to a masters. I have excellent grades but somehow I got stuck in a low spot now. I don't want to work on homework now and I literally wait till the last minute to write papers. I have no idea why because I have time but I rather watch tv or play with my iPhone. I know I should be doin my school work but I don't want to. I also think about the future with my career. It's literally going to take all of my time like you until retirement. Thats a bit depressing even though I'll be making good money. I guess I'm really not adding much but your not alone. The thing that really keeps me going is also my kids and I love peoples reactions when they hear my grades. Perhaps you should forgive yourself and take a semester off so you can relax for a while. Maybe you'll end up missing school and get motivated again or find something else you rather do. Try not to be so hard on yourself and if your doing so good give yourself that break so you don't mess up what youve been working so hard for. That's what I would do anyway. I'm actually planning a break next year because I'll be so close to my bachelors and gaining real world experience for the next level. I'm seriously thinking about taking a yoga class or something.
