where I live the allergy level is very high most of the year ... as a child i was treated for anxiety when it really was allergies ... took many years and a lot of stressful times before I figured that out ... still to this day sometimes I have to guess whether my stress is rising or just an allergy... so I take an antihistmine first and only if it does nothing then my prn ... also when they beat you done it can make you feel like depression ... except it eases faster if the weather changes ...
