Welcome,
It sounds like the best thing you can do is take it slow and start a gradual fade. Depending on your circumstance, you could fiegn some sort of malady like depression or anxiety. These work well because so many of the rank and file witnesses have either or both of these.
My fade was based on my high blood pressure which I did have while on the watchtower wheel (two BP medications per day) down to one small med now and now BP problems.
Depending on how close you are to your family this tactic may very. Use your imagination on what excuses you start to use for missing meetings.
