@Letj,
I think part of what makes my story seem remarkable is that people picture themselves at that age (or an 8 year old close to them) in that situation. Based on my limited experiences, most 8 year olds who had caregivers who weren't able to provide for them for some reason also learned to be independent from a very young age. The step from their stories to mine is not as large as you might think. In many cases I was fortunate because I didn't have to assume responsibility for a toddler or a parent.
I don't want to redirect the attention of this thread to my story when there are so many others that deserve to be voiced. Feel free to PM me with questions and I'd be happy to answer them. To address your second question, I met my mother again 5 years ago. She is remarried and according to some sources sober now. She is in denial of how our years together passed and that may be for the best. I wouldn't consider us reconciled but we each know the other is okay.
