I'm sorry for you. You have to create imaginary characters because you are afraid no one would be interested in the real you. Maybe you think there's no real you. Perhaps it's been destroyed. Oh how I wish I would be so fakely powerful. There's nothing more sad than when people hide themselves and create masks. That shows incredibly low self esteem and vulnerability.
I know because sometimes I play roles in order to fit in. It's a result of trauma. I'm very sorry for you that your symptoms are even more serious. I hope you get the help you deserve.
Or perhaps what you say here is just your wish... Because you openly state you lie, so we can never know wether you're telling the truth here, right? I don't think this statement would insult you because your ability to lie is something you seem to be very proud of.
