I was also thinking about U.Maine or UNH when reading your post. U.Mass Lowell or Dartmouth or Boston might be possibilities. I agree with the other comment that suggested URI. Roger Williams (in Rhode Island) also comes to mind.
To me UVM looks like a reach, and likely to be expensive out of state without merit aid. UVM is good for environmental science. Premed and pre-vet classes at UVM are quite academically demanding (UVM has a very good pre-vet program), and a biology major would overlap with these classes.
I would try to keep your grades up for this coming year (your senior year). On the one hand this will help prepare you for university. Also, in some cases some universities will ask for mid year grades from senior year of high school. With a somewhat uneven high school record this seems entirely possible in your case. Also if you were to start in community college and seek to transfer after one year your senior year grades would be looked at.
By the way, a lot of students had a tough time with the COVID pandemic. I do not know how university admissions will look at this, but you certainly have a lot of company. My daughter who was in university at the time says that it was really lousy (but used stronger language).
