I'm not sure if this would help you or not, but when I get like that, I try to think of it like I would if I had the flu. I think to myself "this is just part of my illness. It sucks, it's miserable, I hate feeling like this, but it WILL pass!" Depression is a dense fog that we can't see through, but just because we can't "see"better things ahead, it doesn't mean that they're not there. All is not lost just because there is a veil in front of our eyes. I hope this burden is lifted off of you very soon! I wish you all the best!
