Sounds like you are trying to find meaning in those lost years. It is natural to want to dive deep into the time that was stolen. All of my twenties were gone, nothing good came from them, but good things did happen to me at certain points. The I lost it all. So the way I see it, I can still see the brief moments of happiness I had, but it is in a sad way, because Alcohol destroyed it all, robbed me of it and left me suicidal and alone.
So yes, I agree that there is some beauty in life's worse and lowest moments, and I see you trying to appreciate those, but you now that you have let it out, let that go and remember where you ended up because of it. Here, seeking help and looking for meaning on robbed time. You don't have to look anymore, you WILL have meaning in your life moving forward as long as you stay sober.
