I pretend to be a teenager on various forums because I wish I never grew up.
That's an odd wish. Why do you want to pretend to still be a teenager?
I'm just trying to relive the good ol' days when I could be myself.
I understand wanting to relive your youth but lying to people online is wrong. You should present yourself honestly online.
But would that be who I am? I think I would still be who I am if I don't lie
I understand the identity crisis, I too, still feel like a teenager! But you should be more honest with yourself and accept who you are so you can look forward to the future. Instead of feigning who you are, why not try role-playing instead so you can play as a teenager legitimately?
