I know the feeling well. And I can relate to being triggered by a dream. That happens to me a lot. It's definitely not easy to just pull yourself out of bed. But I feel it's necessary. I try to fight my depression by doing opposite action. I force myself out of bed and at least onto the couch. I try to do my chores, if only for 10-15 minutes at a time. I play with my son, again maybe for only 15 minutes but I try. It helps a little.

I hope you find some relief soon.
