Well, I'm mentally ill and I frequently have things physically wrong with me. I do, however, have two things going for me when it comes to getting health professionals to take me seriously: I am the proud possessor of a fully-functional Y chromosome and, consequent on the foregoing, a large and manly beard. I am assumed, therefore, to be bearing my condition with stoicism and dignity and would only be troubling the doctor if it were actually serious.
Seriously, get yourself those things - a beard, at the very least - and your healthcare frustrations will just evaporate.
