Turning 40 in 2 weeks, freshly divorced, starting over, advice appreciated.

Im turning 40 in 2 weeks, my wife of 15 years divorced and mooved out last week. We agreed on 50/50 care with our 10yo daughter. I keep the house, she keeps the money. I have a good job only working part time (+ my art side hustle) with 100% home office. No debt at the bank. So basically i could start over a new life. I would appreciate some advice how to handle my new situation.
