Autoimmune disease and thrombocytopenia

Hello, I am reaching out to see if anyone else has experience with an autoimmune disease that includes thrombocytopenia. I’m 5’ 4” - 115 lbs and 56 years old. I’ve been an avid athlete all my life and eat a very well-balanced diet. At age 49 I had a heart attack. It seems my blood is either too thin or too thick and my trigger is a change in the weather or stress. I’ve never been able to tolerate birth-control/estrogen. I have three children. My hormones have reached havoc on me throughout the years. I have regular visits to the oncologist for bloodwork to Monitor my platelet count. I believe my father now passed on at age 92 had an autoimmune disease. I wish to discover more for my children and what more I can do as I age. One of my daughters has epilepsy. We finally better understand my issues and how to treat and I’m happy to say I’m extremely healthy and feel terrific.

Is there any new information on auto immune disease and thrombocytopenia and what I need to do to manage my health as I age?
