+1 to CrossFit. It pulled me through the birth of my youngest daughter, three job switches in a fairly short amount of time and the pandemic. Like others have said, it will not solve all your problems, but it will definitely make you feel better about yourself.

I actually came to CrossFit through reading Tucker Max's book "Mate" (ISBN-10: ‎0316375365) which I also recommend you read. Good luck brother.
