Need ideas!

I am 24. Been pretty much NEET for the past 8 months with worsening anxiety and depression. There is so much I want to do with my life but I feel completely trapped and paralyzed by my anxieties. I don’t go out, I don’t see anyone, I’m glued to a screen all day. I saw this short film Ctrl Z on YouTube today, and it got me thinking about what things I’d do if I could always come back to a safe point in life if things go wrong. Silly things, random things, grand things. So before I convince myself this is stupid and pointless, I’m asking you for help. What are some small, even random tasks I can do to help me break out of my mental prison just a bit? All kind ideas are very much appreciated here!
