Many schools offer distance online courses that maybe you can take towards your major. Maybe consider a bit of a break to rejuvenate and recharge for a while. I know that is risky considering it's hard to back after leaving for any amount of time, but maybe it's what will work for you.

I know how it feels, I'm going on my fifth year of college and I have lost count of how many breakdowns I have endured up to this point, a few I will never forget. I'm also an accounting major, so I was asking for more stress I suppose lol.

Feel free to message me if you need more advice, or just someone to listen.
