I'm pretty sure mine stemmed from being very young (I was somewhere between 3-5). My mother decided to have a harmless alcohol filled gathering with some friends.. Long story short, she ended up being very ill.. several times.. in front of me. Meanwhile, a man (that I didn't know) at the gathering had me on his shoulders.. as I watched my mother be sick.. so the whole experience was pretty traumatizing for me as a child. I didn't really understand what was going on and nobody cared to explain it to me.. mixed in with the fact that strangers were around and I felt unsafe (and we were outside of a gas station at night).. Just a bunch of unsafe feelings as I watched my mother be ill. Scary at the time. This story makes my mother sounds pretty bad lol but I promise she was an amazing parent..
