Eugenia - you are definitely not alone in feeling that way. I chose to leave my mothers group partly due to not have enough in common with the majority of the mums, I had been "attacked" over my parenting choices and found out another mum (who I was the only one to befriend when she started) started bad mouthing my parenting.

It can be very tough at times, I found BB helped a bit and I have since gotten off my behind and finally gotten along to some ABA meetings. The loneliness some days can get a bit much. I do long to just get together with others who parent in a similar way more often.
