What to do?

So I(m17) have been a biggg porn addict and learnt how to do it on 1st May,2022 and have been doing it multiple times ever since. I am not kidding when I say that I bust like 16 times on a normal day. I have my boards from 17th and haven't studied shit and I have tried and have been trying since the start of my 12th grade to study but somehow I couldn't. In December I pinpointed me being unable to study being because of excessive masturbation. I had tried twice before over the years but couldn't last more than 3 days. IIT was my dream since childhood but I somehow persuaded my parents to let me continue normal 12th as I "didn't want to become an IITian." It was because I was an addict and had to choose one thing over the other and now you obviously know which one I chose. Now I have seriously decided to stop it and have a 10 day streak. But one more IMPORTANT info is that I've been so addicted to it that my whole skin's gone numb and I can't feel anything. It feels like whenever your 'leg sleeps'. I can't concentrate although I've tried, trust me I have and I am unable to quit too. Today I went to a pharmacy and the pharmacist is a dude somewhat older than me. I asked him for medicine for porn addiction(Really dawg I asked him although it would literally have been better to tell a pharmacist about a drug addiction frfr) and he told me that I'd have to get a prescription from a psychiatrist. I really want to get fixed but shit I haven't got the balls to tell my dad about this addiction. It literally would've been better to tell someone about a drug or alcohol addiction. I am really conflicted because I seriously need help guys and even I know it. What should I do?? Tldr:I bust 16 times a day and want to stop, should I go to a psychiatrist or not?
