i am 16 years..these days i breathe fast like never before ,yesterday i was so nervous about something and i started to breathe so fast and felt so tired then i fainted.

today i woke up and felt pain in my chest and was so dizzy..i just rested for awhile but still tired and feel like im not stable to move or even walk .. my friend told me to see if i got high fever and i found it 103 F 

all i did was just resting at home and didnt go out with friends but should i take this seriously and see a doc or its a simple thing and nothing to worry about??!!
