Hey. Here are a couple of things that helped me
1) Try and make a schedule each day of the school-related items you need to do. Prioritize by what needs to get done first.
2) Don't leave things to the last minute. Start early so you don't get overwhelmed.
3) Get enough sleep and eat healthy.
4) Get some fresh air everyday.
5) Study with a group. Make games or some fun activity that helps you learn the material in a creative way.
6) If things get too overwhelming, talk to the profs. Some are understanding and willing to help.
The most important thing: Don't be hard on yourself!
