I cheated on my math test today. Feels bad, man.
I can understand that - I think all of us, at one point or another, did something we were ashamed of.  
I know...I'm not sure if I will ever be able to sleep again.
I know that feeling, kinda sick to your stomach can't get it out of your head kinda thing.  We all have to have a method to overcome it and move on.
