Why do so many people think no diagnosis = no problem?
Why do so many people think that if you haven't been diagnosed with anything, then there is nothing wrong with you and your problems must not be real?
It's often tricky to find the root of the problem, so it can take a long time to diagnose. If somebody has an undiagnosed problem, it doesn't mean that there is no problem, it just means that it has not been identified yet.
People refuse to be understanding and considerate and rather treat you like dirt and accuse you of various things and show intolerance until you can prove that your problem is real and that you are not just making up excuses.
Do people seriously think problems don't exist if they are not obvious and quickly provable?
I think you misunderstood me. What I mean is why do people accuse others of being liars, making up excuses or "it's all in your head" when the person knows that something is wrong but doctors have not diagnosed them yet? For example when my hearing suddenly got worse, people didn't believe me when I said I didn't hear well anymore. Instead of just taking my word for it and speaking up, they decided to accuse me of lying or not listening or said I'm just imagining stuff and refused to repeat themselves or speak louder and got annoyed or angry with me for asking them to. Do people really need to see a doctor's note confirming that the problem is real in order to believe the person and stop treating them like dirt? I'm so tired of this, because this has happened with every damn longterm health problem/disability I've had and I've seen it happen to other people too.
