I think you need to stop overthinking. Yes it can make you sick, but the only thing you can do is be on the lookout for it and be smart about avoiding it. I've had around 4-5 ticks in the last years, my kids and family probably around 15-20, one recently near my ankle that probably could've been avoided if I wasn't wearing short trousers. But anyway nobody ever got sick from it and we live in a region with a high prevalence of tick caused encephalitis. There's a vaccine for that so we're all vaccinated now.

Otherwise just enjoy your life.
