acceptance is a hard one for sure. I know I am still struggling with that one, will for awhile. And some days are definitely harder than others when you feel bombarded and ambushed by so many emotions all at once. It's overwhelming.
You mentioned when sober you excelled!!! try to focus on that. You KNOW what you are capable of doing, you've done it before
so...do it again!!! and build up those good feelings! RE-INVENT yourself moving forward.
