I did this exact same thing. I even used to take my cloths off to try and get a laugh. I did the strangest out of control stuff and I never could figure why I did it.
My very first diagnosis was ADHD and then bipolar, I’m sure there was OCD in there. Along with severe hyper activity. I was hyper hyper.
When I was 10 and 11 I was a goner. I had the delusions and the voices and the works. I was sure the voice was my kid sister talking to me from my Mom’s belly.
The embarrassing part… I was sure she told me her name long before my parents even knew she was a girl. I kept calling the growing tummy bump Riley. It stuck, my sister’s name is Riley. But it turns out… that was the neighbors Dog’s name.
