I do not have any friends at the moment except my mum and brother.
Through out my childhood to early teenage years, was completely oblivious to what a friendship was and never really considered or knew that having a friend was a possibility. When I was not overwhelmed by the world or when I was not pre-occupied with hallucinations I was experiencing, I would spend a lot off time reading, content in my own visual mind. Never really needed friendships.
I was always too overwhelmed by some internal and external factors (sensory sensitivities, in particular light sensitivity, anxiety, hallucinations, internal world) to communicate with even family and family friend networks, so I just avoid it.
More at peace alone.
