I support whatever you and your therapist decide is the best first step.

Change is scary. Staying the way you are is even scarier to us. I think age might have a hand in our loss of bravery. Familial and financial responsibilities might contribute that that fear.

You could think about how you want things to play out. It would just be a plan with no dates. What can change with the least amount of collateral damage. What path is least worst...
Possibly these things will cause a minor rumble of an adrenaline surge so you can remember how pleasurable living is again.

When will you put yourself first. Stuff like that. Start writing thoughts down. I'll do it too and we can compare notes, if you like..(I'm adrift and stuck also)
