Actually, I can do everything you said I couldn't, be everything you said I wouldn't. God made me and He says I can so watch me! I will break through those negative opinions and continue making my life amazing!
And you can't make them un-happen. You don't get do-overs, you can't roll back the clock, and the only thing you can change, and the only thing it does any good to worry about is how you let them affect you.
