Our happy son aged 19 out of nowhere with never having any mental health problems suddenly is horrified of obtrusive sexual thoughts towards his sibling and children if he goes out, he is so scared and we are struggling to help him best. We wonder if he is very low in vitamin d? We do not understand how OCD intrusive thoughts can just start when he was so happy and content with life? He has been like this for 1 week now and it started when we were on a walk, daily exercise, and chatted to a cute baby.
