10.2 High pollen today in Co Springs – arghhh

I am sneezing the whole day and the reason is the high pollens around my place. According to pollen.com the pollen today Sunday May 7 2017 is as high as 10.5. That is due to the pollens from maple, elm and juniper. OMG, when can I be friends with these tree pollens huh! When I was new living in the springs, I have lots of immunity against these pollens. But after living in the US for more than 10 years, I don’t have immunity anymore. Why oh why?
