i think you should go see a psychologist. perhaps who
specializes in cognitive behavioural therapy...?
unless there's other issues, this should not be too hard to
'correct'.....
erm....for now, you can try talking to yourself (in your head).
like...keep repeating to yourself that it's just a panic attack and
that you aren't actually going to puke. or once you feel like you
are going into a panic attack, drop everything (if possible),
relax, take deep breaths. find something to do that will either
distract you or will calm you down...idk if these will work for u
anot lah.
