Hi Wildwood, and welcome. I can definitely understand you being upset at them pulling the plug -- thinking you had counselling lined up and then have it pulled away abruptly.
That being said, since you have read the AVRT stuff and made your BP, you really have everything you need to quit permanently. This problem with the counseling need not derail you, and any thought otherwise is AV.
I'm not discouraging the counseling at all -- I hope that you're able to access counseling and any other supports to help improve your life. I would just suggest that abstaining from alcohol does not depend on that-- you can go right along with your BP no matter what they do.
There are some great threads here with a ton of good info -- maybe check out the stickies at the top of the secular forum? Also feel free to post your thoughts and questions -- there are lots of good folks here who will support you.
