I'm sorry you are in this situation. Since your depression is so severe, I suggest that you contact your T immediately for some guidance. If you are so unable to take care of yourself due to depression, then you might need meds and perhaps hospitalization. I'm sure the rent being paid isn't the only big issue for you.

I'm also sorry that you've burned out your friends, whether they understand depression or not. I hope you can speak to your landlord at least.

It isn't the end of the world, but perhaps the end of living this way? Do your best.
