I'm sorry you're going through this. I have to agree with you, it is very hard when it's something that nobody can see so they question you. My own sister has been kind of nasty about this. Her ignorant comment to me was "when you were little you always got the all the attention". I'm not going to get into that because its crazy nor was it true. I'm her younger sister and that hurt. I should not have been surprised. Then I ended up at the emergency room five times because of long covid. This is before they had a name for it. The emergency room doctor did not believe me ask me if I had been drinking. I may have an occasional once a month glass of wine. Then she told me to prove her wrong. That put me in a backward spiral. For the people who don't understand what you're going through, it's on them. It has only been the hospital, and my sister everybody else has been wonderful, including my husband. Hang in there!
