I'm not sure why you say hurt feelings, rather than just "feelings".

On a separate note, historically, the medical profession has been terrible at ignoring or dismissing real issues that people have faced because we didn't have an understanding of them at the time. There's a very strong positivist bent that, if we don't formally understand an issue then it doesn't exist. Which completely ignores the fact that our knowledge of the body and brain and all their complexities (and all the ways they can vary and go wrong and so forth) was and is quite incomplete.

The attitude that, if we don't have an objective theoretical account of some mental/physical then the right thing to do is basically discount its reality has led to so much needless suffering.

This of course is not itself any evidence that someone's claims about themselves is true, but it is something that should always be seriously taken into consideration.
