Anyone have any tips for quitting watching porn? Realized how bad and fucked up it is, and with OCD its just an unnecesarry habit

I'm 17 years old I struggle with addiction I have a problem when I masterbate I have intrusive thoughts idk if I think them I'm so scared also back then I know when I was younger I looked at obscure things hentai all that my idk what to do even I feel like I'm a monster or im a bad person I need help I feel so distraught I feel like I can't live life to the fullest anymore even from last year I looked at content that was animated but it had a character in it that was underage I felt so ashamed and felt like a monster I had a compulsion to check it only to find out they are not around my age range idk what to do I probably sound like a freak I'm sorry I'm always trying to replay my memory and try to remember my intention and what I was doing how I come across how I was doing a action yk all that

I am a girl's in my twenties. I got diagnosed with OCD last year. I have a boyfriend, sadly we're long distance right now. I've liked boys all my life. It's very difficult to sustain intimacy in a long distance relationship. Sometimes I have intimate calls with my boyfriend and it's nice. Other times, however, (and I am not proud of it) I do watch porn. I started watching porn when I was 16. I've tried to quit it many times but every couple of weeks I go back to it. And as everyone knows, one of the MANY problems with it is that your brain will always ask for more. More taboo things, more explicit things. I have a daddy kink. I've roleplayed with my boyfriend and watched porn of this kink. Now, the thing is that my brain keeps telling me that I won't orgasm unless I think of little girls being ab*sed. I've never looked for that on the internet, I never want to either. I am under EXTREME DISTRESS, because what my brain tells me feels SO REAL, and it's like my pleasure gets blocked and that contributes to me thinking my brain must be right. It wasn't like this before. I want to go back. I'm scared it will be like this forever now.

Guys I just wanted to hang up and I was looking at pornography every time I was you know do it and I would get bombarded with thoughts I'd get overwhelmed with them like my mind is just constantly thinking of and it was just so hard infuriating I was looking at like anime pornography and Isaw one of the videos that looks familiar I watched it before but I remember they had like a underage anime character and then I clicked off it as soon as I saw them and my mom said oh you clicked it just so you can see that and what makes it worse is like pretty ejaculation already leaked out so now it feels like I did it i didn't even jerk off to you all I did was see the thumbnail and then I have thoughts like saying oh well might as well already get off to it when it wasnt the content I wanted to see I seen that the thumbnail before in the sight I just ignored it was focusing on the video I wanted to see for now I feel like i have to restart everything not only with the overwhelming thoughts but also my thoughts made it feel like I was actively seeking it like if I want my thought it was like oh you knew it was going to be there but u still click it anyway oh yes I had a feeling but as soon as I saw it I clicked off I don't know I'm just overthinking I guess and also like as soon as I saw it like my mind had a urge like might aswell get off to it finish it very hard I don't even remember how I climaxed I don't even know if I did it right but now I feel like I have to restart
