Fear of choking

So I know I have anxiety for quite a while now. At first it was just me being depressed a little then when the depression was gone I started having panic attacks . When I learned how to handle them, I recently started fearing of stop breathing. Like I would only have a panic attack really rarely but I Am focusing on my breathing 24/7 and when I focus on it a lot I can hear it really loud and it alerts me because when I hear it it sounds scary and abnormal and I keep having thoughts that maybe I have something wrong with my lungs. It's really really hard to distract myself from thinking because even when I'm doing something it's always in the back of my head. I'm thinking of starting to take medication because I have it for years and I can't cope with it anymore and I feel like medication is the only way?

did anyone else experience something like this? Am I in danger or this is actually just anxiety? Will medication help ? I really tried everything else. But nothing seems to work and honestly I don't have any stress in my life at all I would say my life is close to perfect really the only anxiety I have is about my health and my breathing.
