I Cleaned My Bathroom Earlier With Bleach And The Smell

I cleaned my bathroom earlier with bleach and the smell was strong so I opened the windows to ventilate the apartment. That was a few hours ago and the smell didn't seem to dissipate like I thought it would. I began to feel nauseous and develop a headache and decided to sit out on the steps. That did nothing to make me feel better, so I'm in my car with the ac on hi hoping to force fresh air at myself. I'm only slightly better. Is there something else I can do to speed the process up of feeling better without seeing a doctor??
Thanks for your help
