I'm going to take my kids away from their mom
Has she given you a reason to take the kids from her?
Yes, she is so hopelessly drunk to take care of her kids...
If she is not sober, I do not blame you. Drunk parents are not really capable of taking care of their children the right way.
It's my fault for leaving them home alone with her. I thought the kids were mature and responsible enough to look after themselves. Shit happens.
You should make sure your kids are safe, and if you can, try and get their mom some help. It sounds like she needs to go to rehab. In the meantime, you should definitely take custody of your kids and make sure they are in a safe living environment.
