This isn't a radical change but it's a shift and a new form of therapy. Do you know how to play any instruments? If you do, great but learn a new one. Pick up on a different instrument and learn it in and out. Focus on it, make it a part of your life. You could do the same with drawing, or hell, build something from a few slabs of wood.
I don't have any tips for drastic change, but picking up a new hobby you enjoy can bring that about in a positive way.

Good luck.
