Nyororin: to be quite honest, I can relate to your family issues about 90%.
When I was 5 through 9, I had to literally be the parent of the house because both my mom and dad were alcoholics, going somewhere to get drunk. I have 5 siblings (meaning I can now baby sit very good </joke>....
when I turned 10, I was finally moved into a foster home, but lived with my mom again a year later.
However, I only ended up skipping perhaps 2-3 days of school (a year) to take care of my siblings, the rest of the days, we had an actual baby sitter.
Even after all that happening, though, I still love and respect my mom. Why? cuz she's now been in AA for 10 years, she doesn't gamble anymore, and yeah, she realised she wanted to change after that Foster care experience, and it made her better.
Thank you, though, for sharing your story
