I come from 2 parents who were constantly working, I'm disabled and was heavily bullied therefore I became severely introverted to the point one of my first experiences in school was my parents attempting to get me to socialize. This means I spent the majority of my life very isolated from my peers due to my own volation, their young disgust for the disabled and my parents work schedule and violent relationship.
Naturally, this means I did what every only child has done, played by myself. Which now looking back meant me as young as 5 playing scenarios by myself, by 8 I knew these scenarios were very fake and I was essentially playing pretend but I vividly remember my eager waiting for my parents to leave so I could prance around and loudly act out these scenarios. As I've gotten older, I've not only avoided people on the bus with headphones and talking to myself. Sometimes I don't even realize I'm talking to myself. That was at 14, I'm now 20 and it's much worse.
I avoid people to spend hours at a time daydreaming, I'll discociate for hours in a daydream, my daydreams will bleed into my sleeping dreams. I take constant breaks during any tasks I do to daydream. During conversation my mind wanders, art is my main hobby and now I've started drawing out these characters both original characters of mine and different fictional ones. I love writing, I lose myself in the worlds I create them I don't write.
I genuinely don't know how to stop, it's in everything I do, for as long as I can remember.
