Yeah? I came straight here because the top results I saw were recommending stuff like Tai Chi. Not that there’s anything wrong with exercising, yoga, or the like, it just doesn’t feel like a physical problem. I will try walking, but I still think it might be more of a mental issue.

There's barely any separation between physical and mental in this way. If you persist with mental issues without fixing them, you will get physical problems. If you're doing really well physically, it will to some extent assist with your mental health.

That said, you can always do both :)

Sounds good to me. Will do.
