Religious OCD
I have a family member with OCD so I advise you again to get a specialist help you can be treated why do you want to continue suffering? You can’t push these thoughts away. Only thing to do is ignore them, don’t act on them. If you have done wudu once don’t do it again. The more you listen to these thoughts the more they will come. Read up on OCD and you will see the causes of choice of treatments. Don’t punish yourself please get treatment. InshaaAllah it will work.
+1 on seeing a doc!
