Is there anyone here with complex chronic illness that has a positive experience?

That’s it. That’s the question. I am likely being forced onto KP insurance in March, and I’m scared because of the horror stories I’ve heard, as well as all of the specialty labs and ideas my current doctor team is working through on me to determine what other issues I have and how to treat. I’m also worried about my meds not being covered. I have an autoimmune disease, chronic migraine, chronic fatigue, POTS, long covid, SVT, May Thurner Syndrome, arthritis, hyper mobility, chronic venous insufficiency, GERD, immune deficiency, endometriosis, and dysplastic nevus syndrome. I’ll be honest, I have 0 faith based on the stories I’ve read here about KP managing me properly and actually helping me. I currently am on a PPO plan. If will likely lose my job if I don’t make this switch, but I also can’t work if I end up too sick so I would like to hear if anyone has a positive story if they have a lot of problems.
