Does anyone get dizzy with chest pains and feel like they are going to Die? How do you get through that scary feeling?
first, have a checkup with your doctor for peace of mind. then when all is clear, u can, possibly see a counselor for help with the anxiety.
sounds like a typical panic attack 
look up anxiety/panic attack symptoms, thats what brought me my peace of mind knowing that indeed im not dying, as unpleasant and scary as it is, its all just in the head. if you got physically an all clear from your doctor, it may be a good idea to look into therapy to get your fearfulness and anxiety under control.
in the same boat here, been dealing with this for 2-3 years now.
You get used to it after a while and learn a way to deal with it altho it never really goes away
