I'm sorry but all those things sound like good reasons to have CPS called. Maybe CPS isn't the best solution, but your parents not being able to guarantee consistently available drinking water is a big problem. Your mom's boyfriend sounds like a mess of a person and not a great person to have in your life.

The reality is that when parents can't care for their kids, CPS steps in. And it really sounds like there are times at least when your parents aren't able to care for their kids.
