One of my biggest realizations was that even though there is pressure to conform and people say that want you to be this and that. They actually respect you more when you resist them and fight for your identity.
There are times to apologize for who you are but if you're going the apology route, the apology is just the beginning. It'll be a long time of trying to change and winning back peoples trust. Many times, it's better not to apologize, people see that weakness and come down on you twice as hard. It's like taking a hostage, at first you're just relieved the battles over, they surrendered, but then, hey, now I can do whatever I want to them, now they are mine. Then you get sadistic and evil.
