A reality of MLC is that even if this ow completely lets go your H will probably look for another band aid while in Replay.
I think it's entirely normal to have thoughts that you may be wasting your time. I've had those thoughts, too.
You know what? I have figured out that I'm really not wasting my time because I'm using it to work on me and to navigate through my own journey. I'm going to be ready for my new R, (if I'm blessed again) whether it's with my H or someone else.
