I am so sorry you're going through this. I read your other post about your girlfriend being in a psych ward. Has she been diagnosed with mental illness or did she just have a psychotic break? Has this happened before? I understand why her daughter would be angry. The important thing and priority right now is getting your girlfriend well. Another priority is taking good care of yourself. I know you're having a tough time. Take it one day at a time. I wish I knew what to say about her daughter, bless her heart, but just continue to be there for her and be supportive. I wish you well and I hope your gf gets better soon.
