Struggling with depression and insomnia

It’s almost 5 am and I can’t sleep. It’s like falling asleep is too quiet and that’s when all my thoughts cloud my head. I was sexually assaulted in 2016 and had basically the worst experience you could ever imagine after. I was one of the few who reported what happened, and even though he was found responsible and admitted what he did in writing, I lost all my friends and was embarrassed publicly multiple times. I don’t feel super sad or depressed all the time, in fact, the only reason I really think I have depression is because I can’t get anything done lately. I’m a straight A student who isn’t going to class. I have missing assignments, my room is a mess, I feel proud of myself when I take a shower or do a load of laundry....

I don’t want to continue living like this. I’m in therapy which I hope will help, but does anyone have any other tips?
