My take would be:
Start making friends elsewhere.
Just stop attending meetings but offer no explanation beyond doubts.
Don't accept more than one shepherding visit.
Don't confide or even hang out with old Witness friends.
Make sure you're not seen smoking, attending another church or making out with someone for at least the next year.
Yes this will be difficult for JW family members but the ones that can't handle it will cut you off if you do the long term slow fade anyway, or if you move away and stop attending meetings.
Witnesses train their members to waive the right to privacy (eg. elders prying into the bedroom and now HLC reading your medical records). Reclaim it. Explanations and personal decisions are yours, not a corporations.
