I feel the same way and have a significant urinary problem too --interstitial cystitis (IC), AKA painful bladder syndrome. My bladder lining has been damaged by the disease, my bladder capacity is small, and I need to be able to access a toilet frequently to avoid extreme pain from bladder filling. I have irritable bowel syndrome as well. So obviously travel is a big challenge for me.
At home, I can manage these conditions pretty well by following an IC diet and by taking medicines as needed. To make travel feasible, I have to be extra careful about what I eat and drink, restrict liquid intake, and take medicines as needed. By doing those things, in the past I've been able to take road trips (still with frequent stops) and trips by air (last trip was December 2019). But in the era of COVID-19, I don't think I'll be able to take another trip until the virus is eradicated or an effective, safe vaccine is available.
