well, lately, i got dizzy from car exhaust gas, and then got really tired, and then later on the evening it got minor trembling in my legs and hands (its sorta like a tingly sensation inside)... and then it continued fro 7 days up to today and then the trembling became better, but then i began noticing headaches and pain in areas behind my ears, and pain on my temple and under my temples by checkbone in front of ear area... and the dizziness and tireness continue... i went to a doctor for this and he said i looked stressed and worried at the time.. however, even at school with friends, when my mind is totally off worrying about the car exhaust... i still feel dizzy and tired and always yawning... i hihgly doubt this is anxiety and stress, becuase i have had plenty of worries and anxiety in the past, but no symptoms that are as severe or last this long... so is it more likely to be anxiety or am i really getting sck from the gas?
