Working in a busy restaurant setting is almost certainly hurting you. For many people, going to a restaurant is one of the last things we are able to do successfully again, and it often causes relapses.

Taking a week off would help. Even if you can't take more time off than that, is it possible for you to be reassigned to a less stressful assignment within the restaurant? For example, could you host instead of waiting tables (having to remember orders, etc?)? Or could you bus tables? I don't know the pay differential, but the stress differential could make a big difference for your brain.

Basically, what has happened to your brain is that the things your brain used to be able to do automatically it now has to focus on to be able to do. You are essentially having to re-learn or re-build those pathways in your brain, so it takes lots of mental and physical energy to do your ordinary things.

You do need to have activity, but you need to have a lot less of it than you normally do.

Does this make sense?

I will make a separate post showing natural lifestyle things I learned to optimize my brain health.
