Why does my doctor deny me health care?

I have a rare disease called Hidradentis Supperativa and she keeps turning me away because "I don't look that sick". I can't even set up an appointment to have my ears flushed from so much ear wax build up I'm deaf!
I rely on my parents for transportation since we're poor and can't afford drivers ed. So I can't just switch doctors
