First off, is there a school counselor/psychologist at your school that can you can speak to? It’s most important to get help if you are feeling depressed.
That said, it’s too early to be worried about college and way too early to predict where you will have a chance of admission.
Graduating early is generally not a good idea but again, premature to consider.
Find support at school and get yourself to classes on time (go see teachers during lunch or tell your parents that you need to go in early).
