I don't think there is a single epiphany but rather a set of them that culminate into realizing that it's time for you to get your shit together.
>realizing my obession with a 4chan camwhore was unhealthy and that i needed to do something about it
Probably the opposite of what you expect.
I have kept tabs on them for about 6 years. Realizing that it would be real easy to buy a ticket and "meet" them my goal is to get to a point where I have confidence enough to do just that. Perhaps my most fucked up secret but I want to be able to meet this person face to face in a normal setting and have closure. This obsession gave me much of my initial drive for improvement although I am starting to develop other parts of me that are overtaking this.
>Back Injury
Realized how fragile we are and how my body was already failing me. It kicked me into a frenzy and now I'm on constant a race against time to do something meaningful with my life before it is too late. I was in agony for about a year. I wanted to commit suicide so many times and considered myself a broken human being who would never again have relief from pain. It's been about two years and although it hasn't gone away completely I am much better now.
>Mass Effect 3's Ending
Probably the most petty of them all but this right here ended my gaming addiction for good. I had so much time invested. So much care for the characters that when it ended the way it did I realized that games were just another form of control and that even if it had the best ending of all time it would not have made a difference.
It was another universe, another set of friends(fake but whatever) and another life that I would be leaving yet again. I was tired of that. Same thing with something like anime or manga or a good show that you adore. I hate it when it ends, that empty feeling you get is something I could never get over. So I resolved to make my life something worth investing in like all those games I played. I haven't had a gaming system in about 3 years and haven't had that corrosive compulsion to play games since
>Pink Floyd DsofM
Arguably the most encompassing of them all. I was sitting in my car in a pipeyard at work and as the sun was setting I listened to pink floyd for the first time in my life.
I was blown away by every lyric and every truth they sang. Everything resonated with me but time hit me most of all. I had just had an uneventful 21st birthday, I had wasted the past 3-4 years since I left high school, dropped out of college, and had no real relationships to fall back on, nothing worth saying about my life. The days were hazy and I didn't even realize how much time had flown by. I mean, 4 years since I had left high school, in bad shape, no real prospects or plans for the future, no financial sense, the list just kept going.
Shortly after this I started setting goals and really trying to identify what I wanted out of life. It was probably the best thing that ever happened to me. I have come a long way in the short time since. The clarity about what I want and how to get it from then to now, is like comparing city smog to crystal clear water.
All I can say is don't give up, wherever you are, we're all in this shit together.
