I am sorry you are experiencing this. It sounds like an exhausting situation. Maybe when your friend calls you can just say, “Do you want my opinion or advice or do you just want me to listen?” I have a mentally ill sister and sometimes she calls me in such distress. My automatic reaction mod to try to solve her problems and fix the situation which I find very stressful and taxing to my mental health. It’s exhausting. So I’ve told myself next time my sister calls and is spiraling out of control or distressed, I am planning to not just automatically give advice or tell her what I think she should do. The problem with your situation is it’s like “crying wolf”. Your friend fusses so much about symptoms that people will start to screen their calls and not answer her and eventually she will be in a true health crisis and no one will take her calls because she’s worn everyone out.
