Ween yourself off. Start by mssing every other mid week meeting then reduce to once a month until you are not going to any. Then do the same thing with Sunday meetings. Spend the time you usually spent at meetings in doing things for you - IOW self-care.
FS can be reduced in a similar way. Start by going to the group and say you have to go on RVs and you have an appointment after so you would prefer to go alone. Gradually reduce time spent but continue to put in a fake report of 2hrs or so to keep the secretary of your back. If anyone asks tell them you are fine and act as "normal" as possible during this time you are weening yourself off.
Trust me, once you get a taste of your freedom your mind will start to clear more and more the fog will lift until you want freedom more than you fear change.
