Struggles between inner self

I'm taking the entrance exam to uni in couple of weeks later and I found difficulties in catching up the general learning progress. Since my first year in highschool, those mental health issues seem to be worsening. I started cutting myself a lot and sometimes skipping classes because of not being able to force myself getting out of my bed. Part of me knew that I should be taking a break to recharge my energy but part of me believe that once I stopped studying, I won't be able to get back on track evermore... So what should I do 💔💔
