About an hour into cruise the flight crew noticed a strong chemical; electric; metallic; burning odor coming from both aft lavatories. After briefing as a crew and calling the FD; we searched trash cans; and felt for fire all over the lavatories. After realizing there was no obvious fire; we had the FD pull the circuits of the aft lav water heaters. We waited 20 more minutes and re checked; but the smell became worse. We locked both aft lavatories and completed a beverage service; while checking the lavatories as much as possible throughout; as requested by FD. B FA was in and out at least 10 times; and C probably 8 times. D and A 5 times or less. When we realized our minds were becoming affected; and when our throats burned; eyes watered; and head hurt; we all decided to emergency land in ZZZ. Upon cabin prep; my mind was very dull; overcome by fumes. I felt VERY intoxicated and confused. Registered 4.5% CO almost 5 hours after breathing 20% O2 as administered by EMT crew and at hospital. Still feel dull 4 days later.Monitor air quality in flight. Do not let cabin crew breathe toxic fumes. After accidents; assign helper to affected crew. Do not bombard crew with instructions after air quality incident. Give them time of 3-5 days to recover brain function.
Air carrier Flight Attendant reported a burning odor coming from the aft lavatories. No fire was detected but the Flight Attendant reported feeling ill shortly after. The flight then diverted to the nearest suitable airport.
