I had a similar experience once in AA. A fellow set himself up as judge of my status and declared that I was not an alcoholic in a group meeting. I thought: Great...even the fucking alcoholics don't want me! But I talked with my sponsor about it and he told me no one is appointed to be the "AA police", so I let it go.
But what a bummer that the same guy is standing in your way. Consider going over his head? Or, there may be some other similar programs in your area that you could choose instead.
If you can't move a mountain, go around it.
"When I was a child
I caught a fleeting glimpse
Out of the corner of my eye
I turned to look but it was gone
I cannot put my finger on it now
The child is grown, the dream is gone
And I have become comfortably numb."Pink Floyd
