I think you should tell him, it will be very tough to fight ocd alone.
It will be difficult for him to understand ocd if he had never experienced it, but he can help you in taking professional help as well as your family will understand that you are not well from inside although you look good on the outside.
You can tell him how much these thoughts are troubling you,how irritating are these thoughts.
Ocd does not get better with time, it becomes more of a problem if left untreated.
Should I tell my dad that I have HOCD? He could help me but im scared that he understand it wrong. Should I just tell that I have ocd?
well not taking any professional help and fighting on your own will not do any good. Try to consult a psychiatrist for medicine first and then look for therapy.
First try to talk them, if you don't feel good then you can try other therapists.Its like hit and trial.
I took the help of book for cognitive behavior therapy, i also had the same problem of not having therapy available.
But the treatment of ocd contains therapy as well as medicine so first start medicine and then look for therapy.
If you can not find good therapist you can take help from the book"Overcoming Obsessive Thoughts: How to Gain Control of Your OCD" by christine purdon. This book is mainly for pure o sufferers.
No I havent. I live in finland and here isnt many good therapists.
have you taken any professional help?
