Alot of stuff with drugs and child service has came up in my family, and we're trying to keep my little nieces in the family(Which I don't approve of because this family is messed up

) and their mom found out and she's already snitched on alot of drug dealers and I'm getting scared here. I can move out in acouple of months but I don't know what to do until then. She's crazy and threaten us and also a drug addict, but proven to be smart! Anyone else been through this? I'm not sure what to do and it's messing with my anxiety.
