Coast for a bit, and if you do get the itch to play again at least you'll be in a good place with money to restart.
I was in the same spot a few seasons ago and almost quit, but decided to coast. I just wish I hadn't flushed away lots of money trying to see what the new arena changes were (and I still can't understand why it's structured the way it is). I also realized I find div II more enjoyable, you can experiment with team types a lot more and can set up your own challenges.
