I was doing some repairs on my vehicle yesterday including removing and draining the gas tank, replacing the fuel pump, fuel lines and fuel filter. While having the fuel lines disconnected from the gas tank there were strong fumes coming out as I was leaning over it replacing the fuel pump, lines and filter with my head very close to these fumes for a few hours. I was too preoccupied to realize the strong fumes until I began to feel dizzy and had irritation in my nose. All last night I was dizzy, jittery and irritable. I stayed up to 3:30am reading on google about gasoline exposure as I worry something bad happening to me from toxic fumes. Today I feel spaced out, cant concentrate and have trouble remembering much about yesterday. I am not sure if this is just because of me hyperventilating and being paranoid. I know auto mechanics repair fuel systems every day and are inevitably exposed to gasoline fumes. Somehow my anxiety convinces me this situation was unique and will cause damage. What long term effects will I have from this?
