I am so sorry this happened to you. It is so wrong! I have had some therapists make cruel remarks. I didn't keep them long. Sometimes I like to have some fun with it (if other people can, why can't I?) Like when my husband and I go to a restaurant and the hostess asks "How many?" I look behing me and pretend to count and say "Uumm right now there's about four, but you'd better set us up with extra chairs just in case"
I hope you can limit contact with anyone who hurts you like that. You've been hurt enough.
