I dont know what it is but the heat always makes me angry and very anxious,I had to go inside today because I was sitting outdoors actually talking to people today it was to humid and the sun was burning on my arms i dont mind getting some sunburn but when it is very hot and humid it not only makes me mad and i get very anxious too.Forget it thunderstorm and I said this before just frightens me .I wish i had someone to be with when this happens,hidding on the couch with my blanket over my face because I am so darn scared .
