Hi Mulan,
Are you getting quality sleep? How long are you sleeping at night? Do you have a regular waking up and sleeping schedule? Do you exercise? How's your diet? Are you getting a balanced diet and taking multivitamins? Do you have any diagnosed mental illnesses?

Until I was diagnosed with bipolar disorder, there were periods when I would get a lot of sleep, but it would be broken, restless, etc. So sleeping actually just made me more tired.

If you are really concerned, I suggest that you talk to a counselor or doctor.

I wish you the best of luck, because I can empathize with what you're going through. I'm a 3rd year student in college, and I'm still trying to get the hang of studying and self-care. Feel free to reach out to me via PM anytime.

Best wishes,
Allie
