Anxiety or what is that?

Hi, guys! I'm currently having troubles with something( i don't know how to properly explain this) Cuz i myself don't know what is that. But i will give it a try. It's began a year or two ago(maybe its been with me for my entire life(22 years), but it got noticeable 1-2 years ago, before that i didn't give much damn about that. So, the thing is whenever "bad" happens to my health, body , i instantly start to think like it can lead to dangeous/bad outcome for my body. For instance: I ate something tough/sharp it can scratch my throat and my voice gets worse, or when i went to snowboarding and i fell down, i thought like im gonna lose my teeth and was perma checking whether my teeth are ok, etc. And it happens to me everyday, even when i take hot tea i think it can burn my throat/mouse/stomach. if you got anythig to tell me in an effort to help me, feel free to post. Thank you in advance, dear friends!
