'What to do about deep depression' Listener question

I am suffering severe depression and anxiety at the moment. Nothing helps and I cannot pull myselfout of it. I sleep 18 - 20 hours a day and am still tired when awake. I find it hard to wash. I don’t want to exist like this anymore. I’m on a lot of medication from my Psychiatrist and I tried therapy which didn’t help as i was too I’ll to engage. I know what you speak of touches me, it feels like truth.
