A serious health scare with my lung collapsing so much that it couldn't heal and threatened to collapse the other lung. I thought I was going to die for real. I accepted it. It changed me completely. It put me on a path to figure out what was going on in the world existentially. I became a different person.
Then a breakup with my last serious ex. This happened like 7 years ago. I did not treat her well. I hated my life at the time, was losing tons of weight (I was 135lbs at 6'2"). After the break up (and I thought I was going to marry this girl and have kids...we were talking about this shyt), I moved from Chicago to Houston. I was so lost and didn't know who I was. How could I have turned into this monster and lose that girl? Nothing made sense. I started drinking and doing drugs like crazy. It got so bad that I went to rehab twice. I'm 4.5 years sober now, and I'm still lost.
