Hey Pandas, What Is Your Biggest Regret?

Pushing away my first ever best friend. We were attached at the hip for four years until I developed depression. Through bad coping and a few other unfortunate circumstances (being abused by a different friend, falling in love with someone who wasn't good for me, and a lotta other stuff) I ended up never talking to her again. I was a shitty person to her during those last few months and while what I was going through doesn't really excuse my behavior, I wish I could find her again and talk it out. I think I'm a better person now, or at least growing to be, and I want to apologize for the way things turned out.
