Mine was when I almost lost my best friend because of a fight. I went back to read the messages I had written while splitting and it hit me like a brick wall , not only was I not right in the slightest, I was also being extremely verbally abusive. I was appalled. That was the moment that truly woke my self awareness, I was 17. 

Before that I thought lashing out on people was normal communication because everyone on my family did that to me for even the smallest mistake. Also I was never sorry for the way I defended my self until that moment, good or bad, I never repented. If I knew one thing for sure it was that no one would ever have the opportunity to hurt me.

That fight was like a wake up call for me, what was yours?
