Other than medicine, have you tried any other strategies to help with your depression? I'm thinking of things like good nutrition, exercise, getting out of the house every now and then... or...
(I'm not being heartless; I know it's really hard. I'd just like to know what hasn't worked for you, so we don't suggest something you already know won't help)
Suggestions aside, we can just listen... you don't sound very happy there, but you are hanging on. Good for you. That's *brave*.
