Sakura my birth fear centred on a pathological distrust of all HCPs. I'm definitely still not over it but I'm a hell of a lot better than I was. It's why am obsessive about medical consent and ethics.
You can't live like though as it just ends up in avoidance type behaviour which can put your health at risk. It's not a good place to be. You have to build relationships with HCP and develop trust with them.
I fully appreciate how hard this is, once trust has been broken.
I'd also encourage you to read about individuals and organisations which are working to improve this and to stop the imbalance of power within the doctor patient relationship to see that whilst there are institutional problems, there are people who recognise those issues and are actively working to correct them. I'd recommend the above organisation and someone like Dr Margaret McCartney.
Be mindful of only reading stories like the one you linked to in your OP, as it's not healthy and only reinforcing your negative mindset by effectively being like an echo chamber. Challenge yourself to read stories that go counter to your beliefs.
It's not all bad out there. It could be better, but in order to achieve that you have to remove your own emotional response and develop a rational one which is based in substance of how to change not fear and avoidance strategies.
