How can I get rid of my severe pure o and magical thinking without going to any professionals?

Hello, I was diagnosed with autism and ADHD at 25 years old. I attributed my overthinking to autism but I realised a few months ago that Pure O OCD is the most meaningful explanation for it. I am also an asexual, so I am, simply put, a shitshow of symptoms. I constantly review the past - particularly painful memories. I have a consistent fear of getting cancelled. When I was 18, some YouTubers I followed got accused of sexual misconduct and cancelled. I was obsessed and concerned for them. Others found my obsession strange. I did not like how their lives were ruined over accusation and no trial. (I was naive then to why public accusations are happening, as it is because the legal system often fails to address predatory men.) Even 6 years later, I googled one of them 240 times between January 2020 and April 2020. It was plain obsessive. When I burned bridges, I continued to search the people involved in my past dramas. Often multiple times in the same day with nothing new to see. They would likely be scared if they knew how obsessed I was with them. I have started doing ERP exercises. I wrote a script where I receive public false allegations and my life is ruined. It is forever googleable and I am a complete pariah. Completely unemployable, unliveable, even my family abandons me. I listen to it for 15 minutes on loop per day. What else would you recommend to tackle the ruminating? I wish I had this information at 18. I should have been solving these issues then and enjoying my life, not figuring it all out so much later in life.

It could be possible to treat a severe scrupulosity OCD without taking medication and asking guidance from the psychiatrist? I can't afford for professional consultation 🥹. Can anybody give me some advices on how to deal with these intrusive thoughts? 🙏

I don't have an official OCD diagnosis, although I am near enough certain I have it after a long year of distressing intrusive thoughts and compulsions that have strongly affected my life. Unfortunately though, I do not have the opportunity or the finances to get checked or go to therapy for a good few months at least. Due to this, I have taken it upon myself to teach myself techniques to tackle it and to reduce and not engage in compulsions, as I did not want to take the risk of getting even worse before being able to get help (and desperation lol). For the first time in the past year I feel like I'm finally making some progress in getting better since incorporating these techniques into my life as my symptoms have become more manageable (minus the obvious bad days) at the time being. Is self-recovery actually possible? Has anyone managed to recover without a therapist's help?
