Jehovahs witnesses and drug addiction?

So… I have started getting in contact with some sisters I used to know at the Kingdom Hall. It has been a while, a couple years, and I have yet to tell them I am in drug treatment.

What will they think if I tell them I went voluntary to drug treatment? That I ODed?

I am just wondering what there response will be, because obviously treatment takes a big chunck of time and would interfere if they ever asked me to go to the Kingdom Hall on weekdays.

Any JWs out there… please answer 🙂
Thanks
