My previous startup cost quite a bit both physically and mentally, as you become very invested in an idea and its execution for a long time. Something which helped me a lot was traveling to a new and sunny location, staying for a while without trying to do anything in particular, while simply focusing on recovering through good food, exercise, and socializing with others. If you have the resources, I highly recommend taking a sabbatical to recover and give yourself room to breathe and for your mind to wander. Moving to a new space, at least temporarily, helps you get in contact with new people and ideas. With some time, you'll find some new problem space which interests you, or some other new path you'd like to follow. What really helps you feel less old is spending some time getting in good shape physically and mentally to give you strength for your next adventure. Spend some resources on treating yourself to make that happen. Recovering is definitely possible!
