I was doing some research for a project and some experts have said that it's near impossible to have ADHD and OCD, is that true or is this just another case of the medical community being sexist?

I was doing some research and saw about the narcissistic traits that OCD can create. Is this after the person knows they have OCD? Because I always knew I had it. But it was the classic one, with little quirks. Years later I developed false memory and intrusive thoughts whit my present theme. I was reading this because I was thinking about attraction. And I think I'm only attracted to two people in this life. But I remember from times by I had the feeling to please people. Without any interest and without even having the intention to do it, it was very automatic. So I was constantly focusing on how I was apparently being. I never acted like I was interested, but it was always like I was dealing with people's focuses. To tell you the truth, I've noticed that I do this even in other social interactions. I feel like I'm being watched all the time and so I have to act the way I'd like to be seen, like a sweet and delicate person. To be honest, I thought it had to do with my childhood issues because I was very careless and that got me bullied a lot when I was little kid. So I thought I was super focused on my appearance because of that. And I thought that the agaradar came as a consequence precisely because I was always seen as a grotesque girl because I took little care of myself. I even remember that the compliment that made me happiest was when someone said I was delicate. It made sense to me that it really was that. But after researching more, I realized that there are a lot of impulsive and repetitive things in my actions. And never with any intention. But in a very strange way. So much so that when I was younger I swore that I had some kind of personality disorder because it was very common to act one way one day and another way the next day. Maybe I was just an unstable teenager? Thank u for the help!

(TW- Please don’t read if you have ocd relating to one off/random medical events) ^ ^ ^ ^ okay so this is something I’ve been confused about for YEARS and completely sped up my ocd symptoms, I had a one off seizure a few years ago, it wasn’t a major one but enough to have family take me to the hospital afterwards, I don’t remember anything whilst it was happening and I was unwell at the time too. I did all the tests and nothing came back, even tested for epilepsy but I don’t have that. No one has been able to give me a reason and that set off my ocd since mine is mostly based around things I cant see hurting me or others (contamination ocd) or me making the wrong decision (rOCD, real event etc etc) (no clue I had ocd at this point though, only got diagnosed last year) I know they can be stressed induced too but I remember not feeling that stressed that night and not much was going on… Is there anyone that’s experienced the same thing?? Could it be OCD related at all?

so, i’ve been thinking i have ocd, but my dad said that adhd is really bad in my family, so could it be adhd instead of ocd?
