Hello I Have Been Smelling Gasoline For Awhile Now And

Hello I have been smelling gasoline for awhile now and since we live at the corner lot in a street I have always thought it was from outside. But I'm the only one in the family who smells it... in the beginning it was on and off but now I feel it all the time and its getting very frustrating. Am I sick? I'm reading the comments and seams like I need to visit my Dr.
