I am sorry to hear that you are struggling and feeling hopeless.

When medication wasn't working for my depression, we tried ECT and it brought me out of the deepest depression I ever had. Mind you, I was not functioning well (in the hospital, not showering, not eating, etc). It might be worth bringing up as a last resort option but generally it's saved for when you are no longer functioning well. There are also the memory-related side effects to consider, but when you are at rock bottom, the side effects are worth it.

I know this may sound like a trivial (or even insulting) question, but do you exercise? I find exercise helps my mood tremendously. It's pretty much a natural anti-depressant without all the side effects. I am on an anti-depressant and would venture to say that exercise has done me more good than the medication.
