Why now?

I would like to know WHY, now that I am in my 30's, I suddenly am affected by seasonal allergies? I check the weather and there is a flashing banner that reads. "High pollen counts" TRUST me.. I did not need to read that banner to KNOW that fact. My nose is pouring, my head is throbbing, my eyeballs ache- I only wear my contacts for absolutely necessary things then rip those suckers out. I chased 1000mg of tylenol today with a mouthful of childrens allergy meds b/c I was too miserable to look for adult benadryl. Trust me.. that stuff tastes HORRID!
