I'm convinced I have borderline personality disorder, I think it's an OCD thing and now I'm watching videos on BPD which my therapist told me not to do so now I feel like a failure. By the way every couple of weeks or months I see some symptoms I have in common with mental problems and then start researching and taking online tests. I can't have so many mental illnesses can I? It must just be OCD playing games with me.

I do the same thing, it moved from bpd, to npd, to aspd and all types of things. Once I have one thing in common I convince myself I have to have it and obsess over it. Unfortunately the only way around it is to accept that it’s a possibility. It definitely sounds like it’s ocd tho

I get worried ab having that all the time it sucks, try to accept the possibility that you do. What happens then its not the end of the world. You can’t know right in this second that you do or don’t have it.

OMG, I literally thought I was the only person in the WORLD whose OCD targeted ‘mental disorders’! For me, it started after I watched a tik tok where a girl was talking about autism. Despite having literally NONE of the traits of autism, I felt this pit in my chest and I thought - ‘what if I have it and I just don’t have the self-awareness to know?’ This divulged into MONTHS of online tests, questioning my family, and constantly checking that I wasn’t acting ‘autistically’. No matter how much confirmation I got that I wasn’t autistic, I just couldn’t shake it. It still sort of effects me to this day, but I don’t let it bother me nearly as much as it once did. I literally got my parents to take an online test that checked for childhood autism, and they begrudgingly did it, and it came back with 0 out of like 50 and I was STILL not entirely convinced. It’s a rough obsession to have because the compulsions only last so long before you think you’re just kidding yourself, at least in my case. My therapist told me that if we were to read the DSM back to front, we’d leave thinking we’d have every single mental disorder - on Monday you might feel a little bipolar, on Tuesday you may feel a little BPD, it’s completely normal to have fluctuating moods and feelings towards others etc - obsessions can very easily attach to this, so don’t worry, you’ll be okay!

I have bpd and ocd and adhd and the rest but I also have also think I may have other things I didn't realise this was a compulsion The medical checking I did but I didn't

Sounds like you have mental health obsessions! Internet research, taking quizzes, studying diagnosis and symptom lists, checking yourself for symptoms, etc are all compulsions (ie part of OCD, NOT another diagnosis.) get the ocd in check (through proper treatment with your ocd specialist) and you’ll likely notice that you aren’t as suspicious of having a coexisting disorder.
