Everyone is different, but here are some things to try/keep in mind.
If your school offers free therapy try it. Don't feel bad if you need to try a couple of counselors to find one that works for you. Sometimes just having an outside perspective can help you move forward, or at least not backwards. In the same vein you may need to mix up your medication. I went through like 6 different meds before one that worked for me.
One of the things that works for me is having one thing a day I do regardless of anything else. Even if I just sit in my pajamas all day and cuddle my dog while watching Youtube I will still take a shower. It's one simple thing I do every day regardless so I don't feel like a complete failure of a human being. I know some people who go outside for 30 minutes every day. Or do the dishes. Even just opening a window and leaving the bedroom. One thing you can do that is low effort, but makes you feel better. Hell, it can be brushing your teeth.
Try to eat things with nutrients in them. Avoid the junk if possible. I keep a stock of ramen and frozen peas for the days where that's all I can do. It's not great, but it's better than a bag of chips. Those microwavable bowls of soup are good too. Low effort, actual food. It makes a difference.
Don't be afraid to lean on your friends. Let them know you're having a hard time and if they can do anything. Even if it's just coming over and watching a movie with you. I find it useful to be pulled out of my depression cave, but maybe you would like someone to spend some time with you in your cave.
Set yourself a sleep schedule. Go to bed at X and wake up at Y. An erratic sleep schedule is hell on your mental health.
Speaking of depression caves. Don't set things up so you can do everything from one place in your dorm room/apartment/whatever. Make sure you have to move to do different tasks. Use your bed for sleep only, don't lay in it and watch tv/youtube/whatever or read or do homework. Make yourself leave it to do all of that. If you're in the dorm maybe make a point to take your homework to a common area everyday. I'm not saying you have to do your homework, but take it there for a visit. Spend as much time as you can. Eventually you'll get up to doing the homework.
If you're feeling up to it try to clean one thing a day. And by clean I mean maybe throw away some garbage, pick up a piece of clothing, wash a dish. Start small. No judgement, true story: I once let a bug live in my silverware drawer for two weeks because I just was not able to deal with it. I just used the same fork and spoon that was already out of the drawer. I was very disgusted with myself when the depression cloud lifted, but at the time it was just easier to wash the two pieces of silverware not in the drawer than to deal with the drawer. Do what you can do and don't get too down about the things you can't do. You'll get to them when you're able.
Edited to add: This is from 20+ years of clinical depression and 2 suicide attempts. One of the things I can say is that it might not get better, but it'll get easier because you'll get better at handling it. Once you start identifying the symptoms and signs of an upcoming episode be better able to brace yourself. You'll learn to identify the invasive thoughts. You'll figure out your support structure and coping mechanisms.
But really, talk to a therapist.
