It may not work for everyone, but I have tried The Daily Stoic (by Ryan Holiday and Stephen Hamselman) which is a book with daily meditations and passages to read. The general philosophy of stoicism is how to ultimately pass no judgements on external events that are really outside of our control. We all know in this sub that our stutter to a point is outside of our control. Any way, I hope this helps and I'm glad to hear that you have come out of a dark place. Best wishes friend.
