You can search by state. Notice if you live in a blue state, there are public online school options.

I'm not sure how your state is, but I teach in Maryland and our schools have the option where they will send out a teacher to tutor you and you can do your schoolwork at home if you have a medical issue. Which I would think that severe depression *should* qualify. So, you could look into that option as well.
