Daughter psychosis

Family
1

Hi. I’m near here but desperately need help. My 43 year old daughter was a drug addict for 10 years from her 20s through her 30s. The last couple of years she used meth and lost her two children to their father. She became pregnant with another daughter who is now six and has been growing increasingly paranoid. My mother had post partum psychosis and later diagnosed with schizophrenia. My granddaughter is showing signs of anxiety. She chewed off a piece of her hair scrunchy because she thought there might be a tracker I. It. My daughter is now nailing shut her windows. And talking about MKultra I think it’s time to do emergency custody and/ or involuntary treatment but my husband is worried she will commit suicide. I’m so alone and don’t know where to go for advice.
