Would definitely go along with Rayna's suggest for the Al Anon meetings...

Your mother isn't intentionally hurting you, and even if she was, it's not her talking. It's definitely the dope. I recently relapsed and some of the folks here on psych central can tell you I was not a good person. I faught against all advice given to me and I felt as if everyone was attacking me, when really they were trying to help. That's the mind of an active addict. In active addiction, you feel threatened. As if everyones out to get you and you feel you have to take before you get taken from, ya know? Your mom has a terrible addiction that she has to feed right now. Please realize your mom isn't out to hurt you purposely. It's majority the drugs. I know how bad crack cocaine addiction can be, I'm an addict. But I also know that once introduced to recovery and REALLY wanting to get clean/sober, life can change for the better. Try talking to her about getting into NA meetings or even into a treatment program that's a bit more intensive. She may not be willing to listen right now, but at least you tried.
