I'm going to contact child services
For what reason are you planning on calling child services?
I want to help kids in bad situations like my estranged daughter.
I'm so sorry to hear that your daughter is struggling right now. It's definitely important to contact the appropriate authorities if you know a child, be it your daughter or any kid, is being abused or neglected.
I hate my daughter's neglectful mother.
That's a reasonable emotion to feel she truly is being neglectful. If you believe your daughter is being harmed the calling child services is the appropriate course of action.
