I feel you!
I'm 6 years clean from the hard stuff and have had a similar experience. Like who am I? What do I like? I basically got to reinvent myself.
I learned many hard lessons during my dark years, and I decided to use that to my advantage now. I've been through hell, so I don't get fazed by anything at this point!
I'm a 36 year old guitar-playing video-gaming family man! Live life and just enjoy being you whoever you are!
IIRC, that's actually how it was set up to begin with, way back when we used glass bottles for Coke. Big companies manipulated us consumers into thinking we were being lazy for not taking care of recycling ourselves and that's how we got to this mess today.
