When I went through a rough patch many years ago, a much wiser and older friend gave me a quote that I continue to live by and keep in my wallet:

"A wise man recognizes that, although he cannot control what happens to him, he can control how he reacts. As long as he keeps his faith in God and in himself, nothing can permanently defeat him."

I dont know what you did or who you wronged but it takes guts to publicly apologize. Im sure we will all live and let live.
