Things people don’t talk about.

When I got pregnant with my son 3 years ago I developed major OCD, people think ocd means having to be neat and tidy. My ocd is that my brain gets completely fixated on thoughts that nobody especially moms should think of. When I’m pregnant I get fixated on bad things involving my kids. Now I’m pregnant for the 2nd time with my daughter and : For example if I was doing the dishes I’d be scared that I would hurt my son with a knife, and or if I was changing his diaper I would be scared “what if I touched him the wrong way, inappropriately?” Just completely horrible irrational thoughts. It kills me, totally kills me because I love my son, and would never hurt him. My thoughts gets so constant that i almost make me believe myself. How do I stop this? Am I normal? I just want to curl in a ball and cry and cry and scream.
