Hi again @Jane19
Here is a forum tip we share with each other when we first arrive here on the forums .... putting an @ directly in front of someone's username tags them to your response and keys them know who you're talking to .....
OCD is part of the issues in our family .... I have an estranged husband who is caught in it big-time, but unfortunately it has caused him to trash our life and our family at the moment ..... I am picking up the pieces by degrees ..... but our younger son has this struggle in too, and is having to take the baby steps as I suggested to you. It's something that is quite ingrained in my soon2bX's family, as are other patterns that seemed to trigger in him as a mid-life crisis.
I am so glad you have the self-awareness to walk the recovery path ..... I am bearing witness to the effects of when that doesn't happen, unfortunately. He might get the help he needs further down the track, but it's way over now for us for all the other reasons he brought on board.
It might help to set up a bit of a self-reward system, like keeping a little log of your small successes as you go, and setting something special to do / have / buy / visit as a goal to work towards. It can help to take your focus away from the struggle a little, and think about something nice ahead of you.
