My sister has suffered with health anxiety for many years. She lives with my elderly father. I have recently taken a step back from our daily texts between my sister and I. I’ve tried to help her. Suggested many things she could do to help herself a little more. Always been delicate with her. My own mental health is suffering due to the constant negativity and medical problems that she believes she has. My father has pretty much begged me to re- establish contact with her even though he knows I’m at a loss to know what to do next and the fact that I’m under the Dr for anxiety myself. It’s been around 10 years of me trying to help. She doesn’t seem to want to help herself. Should I re-engage?
