You may recall, I posted in your last thread, that I had lost my wife of 45 years. I too considered selling the house and taking the "geographic cure". Supplemented with copious amounts of alcohol. I did not go that way, I am still in the house with no plans to sell. I too sold the RV for the exact reasons you describe. Both turned out to be good choices. I would not presume to tell you what to do, I can only speak for myself. But year and half has passed now, and things are much better.
I don't know if I can live with it, but I have learned to live along side it.
Keep the faith, wishing you the best
