Okay... I'm not too heavily involved in the Reborn community (although I would love to, but I'm a little shy) - so I may be speaking out of hand here - but I'll express my opinions. I haven't got the faintest idea of what exactly happened that made you reveal your true identity - and we never actually had a real conversation - but I know the feeling of impersonating someone.
I won't go into details - but there was a time where I chose to act as a different person. At that time, I was afraid of the people in that particular community - and naturally, I didn't want them to know more about me. Hence I chose to portray myself with a different name, a different birthday, different school, different family members etc. I really thought I wouldn't hold the relationship with that community for a long period of time, so I didn't really regret the decision I made back then. However, I found myself growing more attached to that community - and I began to feel guilty of my actions. But being a naive 20 year-old person back then, I really didn't think it mattered too much - and thought if I told them what my real self is, they would be surprised but that would be it. I had no clue that those kind, always-smiling people would instantly turn their backs on me when I confessed my true self- stating that I have lost their trust by lying when they, unlike me, revealed their true self from the very start - trying to earn my friendship. Strictly speaking, I was devastated in the beginning, but I learnt that I was alright without those people beside me after all. Call me cold - but that seems to be who I am. Nevertheless, I vowed that I won't make the same mistake, ever again.
I do understand why you have chosen to live under a different alias. I'm guessing you felt the same way as me back then. But posting pictures of someone that isn't you, and going further to claim that the person is you is clearly wrong. I also understand that some members of the community that were very close to you will be pretty hostile towards you for now - and you will have to endeavor to earn back their trust. Some may take months or even years to speak with you again - but I'm sure you can achieve that because I can sense sincerity in your posts in this thread - and I think you are willing to fix your mistakes. Good luck.
