I'm Kind Of Freaked Out, I Think I Might Have Leukemia?

Ok so I think i MIGHT. i just want to eliminate it from my theories. for the past moths, like march, i haven't been NOT sick. i have got Bronchitis twice, three viral infections,flu three times, and five sinus infections. i eat pretty healthy, i eat fruits and veggies everyday at school, and only a salad once a week. on Thursdays i eat fries, and on Wednesday i eat Taco Salad. on weekends i eat steak and a salad, or Goulash(Tomato Juice, sausage and/or hamburger, and spices.) i have gym every other day, and we always run 3 lap around our track, or run for 3.5 minutes around the gym. i think i am pretty healthy besides getting sick. i have been finding random bruises on my legs over the past two-three months. when ever my cat scratches me, i always bleed for a couple minutes. i have a few little red spots on my thighs, close to my waist. i am always tired, and i have body aches a lot. This might not have anything to do with it, i lived in a house infested with mold for 11 years, have live in a clean home for almost 3 year, in February. i am really hoping i do not have Leukemia, because i lost my uncle from bone cancer and i know what he went through. i am hoping i dont have it. please help. I am a 13 y.o. girl by the way.

PS if you read my other question, think you might be able to help?
oh and i have been getting headaches almost every day for about a week
