When I was using drugs, I was horrible to my mom. From about 18-23 until I was able to get clean I wasn't able to see my behavior. Though I do feel like I'm very close to my mom now and try to show her the respect she deserves, I can't take back the horrible things I did and said to her when I was high (I was a monster).

Maybe your daughter needs to get through her addictions before she can see how her actions are hurting others. It's very common for a drug addict to blame the world for their problems and deny any self accountability.
