I need tips

Im in Ontario Canada and the city I’m in is having an intense thunderstorm. I’m sick of feeling this anxious every time we get a storm. It gets to the point where I feel like my heart is about to stop. I cant stop shaking I cant breathe properly and I get sent into to crying fits very easily. Does anyone have tips on how to calm myself down? Looking at the weather every 5 minutes to make sure there isn’t a tornado isn’t helping me anymore 😔
