I also have a fear of storms and understand what you are going through. I'm not sure if you have pets or a friend that can be there with you during a storm but I have always found it helpful to be with my dog when it is storming. Petting animals helps to bring down your heart rate, it could also be helpful just to have a friend around for comfort. I also listen to my music to block out some of the noise. I hope this helps you!
