I posted something similar to this a while ago. I couldn't figure out how to word the title, but what I am talking about goes like this:

People will be talking about something and then someone brings up a fact about themselves or a person in the conservation like "she's such a perfectionist" or "all the chairs need to be stacked this way" (mainly OCD symptom things) and then the friend or the person then would say "I must have OCD" or "I probably have OCD". The public makes mental health seem so out of proportion. I hate it when people say "oh that block is in the wrong place, I must have OCD". First of all, most people wouldn't state out loud that they have some mental disorder due to stigma, and second of all, that's too small of an instant.

I want to complain to my school about this because I find this really offending since I do have some mental disorders. I am looking into getting a diagnosis of OCD because it has been getting really bad. I want to run over to the sink every 15 mins to wash my hands because I feel contaminated. I sometimes check things over for 2-3 hours to make sure it's perfect. It's not just "I do this particular action so I have OCD" type of thing.

Anyways, these instances seem to mainly happens with OCD, but I know it happens with other mental disorders too. I heard these kids be like "I have to sit beside my friends all the time, so I probably have separation anxiety". No, you don't; you are just being a teenager who wants to socialize. This angers me. Why do people have to do that? It's so frustrating! Does anyone else hear these type of conversations happening? I see a lot of this in the YouTube comment section.
