I entered a 10 month long distance relationship my sophomore year of college at a UC. It became overwhelming; to give you a picture of the intensity - we were fantasizing about our wedding after we hit the 2 month mark. My membership in a frat had a terrible dehumanizing effect on me, I became cold in the relationship & unresponsive - long story short: there was a falling out that caused me to have a terrible quarter. My GPA fell substantially and I lost a scholarship.
After an unbelievably depressing period of my life, having lost the love of my life, I used that experience to make me bitter, relentless in my studies. For the past year, I have gotten nothing but A's and raised my GPA back up from 3.3 to 3.65. I've regained my scholarship; I've regained my future.
"Life experiences" like this one suck, but they are one hell of a character builder.
