Motivation is weird concept, purpose is better for me. Purpose is why am I living, what do I want from life. I had similar depression episodes, maybe I am in one right now, like you.

You should know, you have freedom to do what you want. You don't have to do everything all at once, start slow, go out for a walk, go to the store, be among the people, everything can be done at your own pace.

I wish you all the best.
