I want out of the service industry, but I can’t leave the money or the flexibility. What else can I do that’ll end my 9+ hours daily on my feet?

I'm really beaten up all the time. I guess I'm just not tough enough. What jobs can I look for? I have stupid degrees in acting (BA and MFA) but I don't think I could handle being a teacher. Is there anything else I can look into? Super lost, a little desperate, and very very very broke.
