TBH after years of making myself try and do things, I now accept how I feel and if I'm so depressed that I just want to stay in bed most of the time, that's what I do. I allow myself to feel sad and withdraw from the world. I think I need that time to be sad. I don't push myself to do stuff. Letting it happen makes it easier for me to recover, because it feels natural. I start doing things only when I feel better. I don't force it.
