I’ve only posted once on this site, basically introducing myself. My heart goes out to you as I’ve gone through this with my 44 yr old daughter on and off for 20+ yrs. One consolation is that she is with her boyfriend, the father of their daughter that I’m raising. I don’t say let go, I say, I’m allowed to move on and live my life each day, in relative peace. I pray for them each day, and obviously hope they are safe and doing something to get their lives together but that’s ultimately up to them. I hope this helps you.
