When my dad was out of work we didn't have health insurance, but he still made sure we got to the doctor, dentist, eye doctor, whole nine yards if we needed to go. See, my parents cared about our physical well-being.
My parents would slap the shit out of your parents. I'm sorry if that sounds mean, but your parents sound like horrible people. This isn't the first time you've mentioned having some kind of health/physical problem and then telling us your parents won't do shit about it.
