Don't you just hate it when you have to admit you've done something wrong? It's seriously like one of the hardest things to do. But when you make a mistake you have to admit your wrong or nothing gets resolved.
I am going through this right now. I have had to admit a mistake I made and its really hard. I was involved in some gossiping and the people found out. So yep, I had to admit I was guilty. I hate that but I was. Even more I'm mad at myself. I hate that I did the one thing I hate so much. I hate that I hurt people and broke people's trust in me. I am mad at myself. I am mad that I didn't choose to be the bigger person. I am hurt that I will probably never be the same in some's eyes because of one simple mistake I made. I wish I had done the right thing.
I guess all this rambling is just to maybe warn/tell you. Always try to do the right thing. Doing the wrong thing is never worth it in the end. And if you do mess up don't be afraid to admit your mistakes. It'll be better doing that in the long wrong.
