Q.) Why do some people in a family have ocd and the others dont

A.) Everyone's circumstances are different, such as my dad watched my sister, mother, brother and me all get anxiety, but he never did. It's just how we handle situations. A lot of time subconsciously anxiety and OCD can be contagious because we see it and subconsciously process to do the same behavior. Sometimes it can get very complicated, but what I would tell you is that once you get over it, you can help the others in your family that may have it and free your family from such an unneccessarhy struggle!
