I used to also be a swimmer, and I know this feel bro. I decided to take up diving though in my junior year, and I found that divers feel almost the same about swimmers. Our pool was small and we would have to practice only after they were swimming back to the shallow end. It made me a bit nervous, having to worry where they were at all times, and I ended up messing up some dives. It's a two-way street bro.
