You're right. I revisit those times frequently with great results. I do it through writing about it, posting here, and immersing myself in a music playlist that recalls the good times.
I don't often post about this since my regimen could be another's trigger---that's another thing I do that could be risky. Sometimes I intentionally visit the dark days through writing and music as well. I think of it as small doses of toxins---to build my immunity. Obviously, I have to be careful to titrate the dose of those visits so I don't recommend it lightly. My T warns me to be cautious---and probably would't have approved when I first took this on.
There are many paths to healing....
All the best.
