How did you choose your schools - it’s an eclectic list.
As you know, Harvard is unlikely for most everyone and you’ll face that. I wouldn’t call Connecticut a safety for you but I do think, since they have so many apply TO, that you’d get in.
You have 3 smaller schools - so why Clemson?
I would certainly find a school that has the counseling services to help you if needed. Many schools are strained.
I hope you get a chance to visit each, learn more about available services and find the right school for you, not just the biggest names.
Good luck.
