Life could be a lot worse. No, really.
Don't think about what you're going to do after you graduate yet, just take it a day at a time. It sounds like there probably is some degree of burnout, of which I'm example no. 1 and am currently working through. I have a few suggestions:
1) Negotiate a more reasonable work/study schedule, something that you can deal with. Talk to a counselor for your options, your situation is common and these counselors have lots of experience with such problems.
2) Transfer course/university. It's pretty drastic though.
3) Acquire skills with time-management, prioritise subjects. You don't need to do everything in your freshman year. Spread out the tougher/must-do classes. I had to learn the hard way that doing 3 lab classes in one semester was not proof of capability, it was suicide.
4) Set aside non-negotiable "me" time, during which you do things that you actually LIKE and that relaxes you. Not necessarily creative things, it can be as simple as listening to music passively in bed with the lights off.
You don't need to be this negative about college or post-college life yet, especially since you haven't had much experience with either. If the signs are that it's not something that you can deal with right now, you can either set out to make it manageable or change yourself so that it will be manageable. As someone who did everything in a rush and tried to maximise every part of my college academic experience, I found that I didn't have much time to make friends, to simply "have fun" or to see anything outside of academia. In other words, I got a quality education, but not much in the way of life experience. Now I'm a washed-up graduate student on anti-depressants and I have to learn to be satisfied with (if not being able to do everything that I thought I needed to do) everything that I CAN do.
So I guess my point here is - there are things that you can do; low energy levels (I don't have much energy either) can be proportioned/prioritised; you can find ways of "recharging"; despondency is premature. What you should not do in this situation, however, is give up and accept things as they are. You'll burnout; probably sooner than I did. It's much harder to come back from that. Working out a study/work/life balance is hard, but it'll be worth it, and an invaluable skill that you'll be able to use forever.
Good luck!
