<human>: Similar to many of these posts, this did not actually happen today.

About 6 months ago I was posed with the absolute biggest opportunity of my life, being able to play the sport that I love abroad in Australia. In the weeks leading up to my departure to this place, and after my high school graduation I was indulging in the many chemo-physical distractions available to myself in the summer, during which I became addicted to cigarettes. I continued to smoke in secrecy through the offseason in Australia, but when practice finally began I realized that it was about high time that I quit. About three days after my 'quitting' I was hit with a soul crushing depressive state that I attributed to homesickness. After about two days, I decided that my best course action was to go home. I spent the rest of my savings on a one way ticket back to the states and reparations to the family/team that spent so much to get me there. In the airport, waiting for my transfer from Melbourne to LA, I decided to treat myself to a cigarette, courtesy of a man in the smokers lounge. Immediately after this cigarette, I had a 180 degree turn in my outlook on the situation I was in, but by then it was too late to turn back.

Can you condense the text into three sentences or less?
<bot>: I gave up on an adventure that many would kill for, just because I mistook cigarette withdrawal for homesickness.
