Great post!
By no means take what I am about to say as me being happy in any way about the drinking person that I was but here's my take.
My life right now is a compilation of all things that have happened to me whether they be positive or negative. If those negative things never occurred I could have never learned from them therefore I would not be the person that I am today without them.
Do I wish that I could change some of those things? Absolutely! However, they are still a part of my learning experience and that's how I choose to reflect on them.
That's what's important.
