Hi my name is Shane and I'm 19 years old. After a bad experience huffing gasoline, which was stupid and I'll never do it again, I've been worrying about my heart, if i damaged it, and been having a lot of anxiety thinking I might have a heart attack. I keep having symptoms of having one but they just come and go, its been like that for 2 months now, I had an EKG test and the doctor said my heart seems fine but i still worry..Had a halter monitor which i wore for a day, that was a week ago and still no word back about the test results..Could huffing gasoline really have damaged my heart? I've been told all this is just Anxiety..
