I don’t really know what to do when I try to explain to someone that I have ocd and then they laugh and say, “but your room is so messy” any suggestions? I’ve tried explaining but they don’t seem to listen...

In some cases the battle may not be worth fighting. You don't owe anyone your mental health info. You can provide examples of different subtypes, but that will probably lead to them asking what your subtype is. Which you may or may not be willing to share. I've told a few trusted friends that I have ocd and examples of a few if my compulsions. Increasing awareness is a good thing, but you can't control what others will believe. Look out for yourself first.

yeah ive experienced this with my sister her and my mother both have had physical compulsions like checking locks multiple times and are very much overly "clean" type people in general so when i tried sharing what i was going through my sister just rejected the idea that i have ocd because its not what she understands it to be and i already live with doubt about having ocd all the time so it really is a punch to the gut especially since i love getting reassurance ... Ive had to learn to stop trying to get her to understand because i think its just for temporary comfort and it wont make the intrusive thoughts go away

i also hate when i recently told a close friend like how my thought spirals work and she tried to tell me she thinks that way too sometimes but it felt like a way of saying thats not ocd all people worry about that and my mind immediately thought shes trying to say i dont have ocd im just being dramatic when i dont think she even meant it that way so im slowly learning to be more selective about talking about my ocd because im very sensitive to peoples responses probably because a part of ocd is living in constant doubt 🤷‍♀️
