I think you are dealing with much more than depression, unfortunately.

Please do ask your therapists for more help, as soon as you can.
I am guessing you are in your 20s or so, since you are so aware of your household's financial problems, and I would hope a parent wouldn't be sharing that with a child.
Hang in there, and stay safe. Stick around ppl as much as you can, it's unfortunate that you can't get a job or do schooling, but some activity rather than being around the house concentrating on just what is happening can be very depressing.
