YES. Actually this was part of the road to realising... Ever since I was 8, my mum then used to play Everquest (mmorpg) and she let me have a character, and I created a male Paladin. And thus began a long and arduous relationship with this game- when I got my own PC in my room with internet I was pretty much addicted to it.
I got that you could be addicted to a game but it felt like more than that, I was addicted to who I was- at the time conceived as the male version of me, and in some ways, then I thought it was a lie. Only when I realised the true nature of why I wanted to exist only in that world and why I'd rather be there than go out with my real life friends did I realise that actually all I was doing was... Being me.
I was addicted to the game, but also to actually being able to just be me and not have to act at all to how people thought I should be. I had to quit the game for exams and I never went back, but I came out not long after. I still miss just being able to be me and not worry about 'passing', but actualising myself in reality... Is far more rewarding.
