So let me get this straight...
Because an rp that you started has failed due to others, you are going to abandon your profile and quit role playing all together? Rps die... it happens. People have things suddenly come up in their real life that they don't wish to tell ghosts online about. Maybe you failed to motivate them enough in your story or maybe you weren't hard enough on your selection process. Could you have started the role play at an inconvenient time for most people and drew a bad hand?
Now I don't know who you are, never met, nor talked to you, but asking for another person to delete your profile and publicly announce that you are leaving is just an immature, attention seeking grab. Either don't say anything and leave (cause no one likes people who think they are more important than who they really are), or turn around and make an effort to talk to other people, generate an identity for yourself and improve your leadership skills for the next Rp.
Everyone fails once in a while and if you can't realise that, life is going to be very hard for you.
