I can’t repeat this enough. You are not responsible for your health conditions.
When I was told I had a incurable chronic illness some people try to tell me what I should have done different not to get sick. People do this instinctively because they are afraid of being in the same situation. If they believe that they somehow have control, then it won’t happen to them.
I was lucky to have amazing doctors who sat me down and made it clear that illness doesn’t care what you’ve done or haven’t done and that I was not responsible for my health conditions.
