Hello I am 18 for a few months I have had stabbing pains in my chest but a few weeks Ago my breathing got terribly hard this discomfort is from when I wake up to when I go asleep then I expierenced dizzy spells ,I am a smoker but haven't smoked in 2weeks due to when I have one pull I can't breath then a few days later I started feeling heavy headed ,it all went in that order ,I went out today to some where I hadn't been I fell really sick in there and felt dizzy like I was going to collapse I was trying to listen to the woman but I felt spaced out and could hear my heart racing this is really effecting my life I had to leave straight away and get in my dads car home with out finishing the meeting any ideas
