It Happened Again!

Ya, It happened again. It's the 2nd time for my 1st sem in Uni. 
Tat day we have workshop at Station One cafe, but there is one woman that is smoking for couple of times when we are there. 
I try my best to bear with it, keep counting my pulse without letting my group mates know. I scared they will worry, I try to act as ntg happened for the whole period, it's really suffering. Finally, I exploded, can't bear it any more.. 
I rush to the toilet to take a breath, same thing happen, whole body paralysis, trembling, my legs can't even support me, feel suffocated, my heart feel like jumping out of me.... Really painful.... 
Fortunately no cramp happened. I ask for help from one of my member to take the plastic bag for me, then I do what the doctor always tell me to do. 
Phew... I feel relieved, then i go walk around the Jaya One, get some fresh air, make myself calm. Ya, that's it, i feel fine again, continue to work!! I really feel scared, it happened more frequently now. I feel that I can't control myself anymore.. 
When only i can overcome it.. I really hope that in the new sem it wont happen any more. Please help me, God. I don't even dare to tell my family, don't want them to worry. 
Haiz.. It's ok! I had came through that attack, ntg serious happened, it makes me appreciate my life more! Thankful.
