I think that a good first step would be to force yourself to go out of your place every day, and to force yourself to talk to people every day, even if just chatting briefly with cashiers.

I acknowledge that it won’t be easy to do these things. Still, activating yourself is an important part of recovery.

Even better would be to walk, run, or swim three days per week. It doesn’t have to be strenuous, simply being active consistently is the main thing.
