Hypchondriac?

Okay, so I’m 15 and over the past year I have gone from having almost no health problems ever to a bunch of different problems. It started of with an invisible rash all over my chin… It itched so bad and then went away after I got cream from the doctor. Then I had this horrible sore throat/mono type thing that took me out of school for four days. On top of that I have had 2 ear infections, plantar faciitis (a foot disease) I have torn tendons in my foot and I have had bone spurs on my heels, along with fracturing my foot I also have had trouble breathing through my nose at night and I am on nasinex for that and I had an asthma attack like thing at my dance comeptition and I have become really prone to sunburn even though I ave iron deffiency anemia (I have sun poisoning right now). My parents are really sick of taking me to the doctors and they are really mean about it they say I am a hypocondriac even though everytime I go to the doctors they do find something wrong so it is not in my head… Right? Plus what could be causing my sudden sickliness? ( mind you this all happend in my freshman year alone)
