Well, the other users have сказал(-а) already how to remove an account, however, I would like to say something personally to you.
I see on your Профиль (and I don't even know if you'll bother to read this after Ты Удалить your account) that BlindBandit92 is asking why you're leaving, and the reason being "being nice gets Ты nowhere". That's partially true, I'm afraid. Being nice will get Ты nowhere...in some situations. Can I personally guarantee that you'll be recognized and treated nicely by being nice to others? No, I can't. Ты don't have to be nice to be recognized. Ты don't have to be nice to be treated nicely by others. Ты just have to act like your true self, like the person Ты are alone. Some people might not respect you, but a handful of others will. I can't stop Ты from leaving. I can't make Ты read this either. All I can say is good luck to you...you're gonna need it.
