Please help my mom!

This is my cry for assistance to help my mom before she breaks. BACKGROUND: My mom underwent surgery for a brain tumor years ago and is 43 now. she also underwent proton therapy and has been cleared for a while. she has always had issue with mental health, specifically depression and anxiety. she was prescribed paxil, viibryd, and busperon. she loved the effect these meds had until the past couple years. her depression, anxiety and irritability is back worse than ever. NOW: My mother has been experiencing hair loss, acne, fatigue, tender breast, tingling sensations, mental breakdowns, hot flashes… the works. our insurance covers next to nothing, and the appointments it has covered have been no help really. the doctors have told her that they do not want to test her because she is so young. they give the same advice over and over, which she does. She takes a multitude of supplements and exercises very frequently. Her diet is carefully watched. She drinks plenty of water. So far, nothing has helped. There is something wrong and I feel helpless when I have to listen to my mother in physical and mental pain, and having every avenue turn her away. If anyone has any type of advice or has experienced this, please help.
