Coping With Ocd

I want to seek professional help to see whether or not I actually have OCD, but my parents, especially my mom (who is a psychiatrist ironically), won’t hear me out and refuse to let me see a doctor. Does anybody know how I could circumvent my parent’s refusal and get in touch with a doctor?

I would have some intrusive thoughts but those thoughts are the same thing and I would seriously get ticked off if it's not right I would also tap the faucet twice and touch the objects with my two hands like for example if I touch something with my left hand my right hand should touch it too and when I saw it once it should be twice and for example my mind would keep and reading stuff reversed like okay yako fine enif and last time I keep on chewing my cheeks
