My mom is going through the same thing right now. I have lived on my own for years since I've graduated from college but I just decided to tell her about having Bipolar Disorder like a year ago. I thought she was okay with it but lately, over the past month or so, she's been all on me about me needing to move home and see doctors there and that I need to stop taking these meds because they are all harming me and that all of my problems in life revolve around me having a bad thyroid even though my thyroid levels are fine. I think just like we have to go through a coping phase when we are given a diagnosis, our family members have to go through the process when they find out about it. Maybe you could share information with her about bipolar disorder. She probably is working under false assumptions about mental illness and she's just being flooded by images of the illness that may not be accurate. Have her look on the NAMI website. They have lots of videos and websites and links that I found to be helpful for my mom. Good luck with working this out. You just keep focusing on wht you need to do for you. Your mom is an adult and she's accountable for her actions. I think with time she will come around and be more supportive. Bravo for having the courage to reach out to her!
