I have OCD and I had problems with my family too, well just my dad. It wasn't about medication, but he hated that I went to therapy. He was afraid I would complain it was his fault I had problems. (OCD and Tourettes were in HIS family, undiagnosed back then). When parents are fearful, they may feel they have to stay in control.

I bet there is a family history of this illness - because it does run in families. They may not tell you this until years later. "Oh yes my grandmother did these strange little things too" - was afraid of germs or disease, couldn't drive because of anxiety, etc, etc.

I'm am SO sorry they are ridiculing you though. You have enough anxiety as it is.
