So just to give a little history... My sister has an undiagnosed mental health issue definitely. I personally believe she has borderline personality disorder due to her intense mood swings, fear of abandonment, and rollercoaster romances....Her boyfriend recently broke up with her and she has not been taking it well. I believe the stress from this break up may have caused some health anxiety for her.
She had a kidney infection a few weeks back and was treated with antibiotics. She followed up with her doctor until the infection cleared....but then about 2 weeks ago she has been convinced that her kidney is failing, despite several visits to her doctor and emergency. They have tested her blood and urine several times and sent her on her way. Since then, she has mentioned several symptoms that sound like anxiety to me (Dizziness, racing heart, nausea, etc) but is now convinced that she has blood poisoning.
I know that in her mind she thinks she is dying, and is scared, and I want to help her. I've gone to the hospital with her and all her doctors appointments as I have been trying to be as supportive as possible. She just thinks that none of the doctors are listening to her and that she has blood poisoning because her kidney failed.
Obviously if something was medically wrong I would want it to be looked at, but I just think a lot of this is actually in her head and exasperated by anxiety. I am trying to figure out how to support her without making her feel like I'm just pushing her concerns aside, but at the same time I don't want to fuel the fire.
Does anyone have any suggestions on what I should tell her or how I should bring the idea of health anxiety up to her? Keeping in mind she is EXTREMELY sensitive to perceived criticism/abandonment/etc.
