I'm sorry, also, Jow. But I'm glad that you seem to be physically safe, and that no one else was harmed.
I don't think I'd have fared well with the "harm reduction" method myself. The rehab sounds like a much safer, saner alternative, and might be the light at the end of the tunnel for you.
Please take care and let us know how you're faring.
I'll be thinking of you.
Big hug,
Donna
