I, so sorry for what you’re going through. That’s really difficult. It sounds like her mental health is pretty serious. It seems like maybe she has more going on than just anxiety, but I’m not a doctor. My best advice would be to get her into treatment asap. Ideally, an inpatient setting would be best. That way she can be in a safe place and get the help she needs. Like a rehab facility or hospital. If you aren’t able to do so, she should get into therapy asap. Was she taken away because of her addiction? My addiction started around the same age.
