I keep piling up qada and I feel guilty

I travel for work so much now that my prayer routine is more like a suggestion than a habit. I sleep in different hotel rooms, eat breakfast at 4 a.m. in some airport lounge, and sometimes I find myself taking wudu in an airplane bathroom because I must step out for a meeting. I have a small green prayer rug rolled in my suitcase and a list of missed prayers on a notes app, but the guilt only grows. I keep promising myself to do qada on flights or on Sundays, and then another week disappears. How do you carry the backlog without letting it crush you?
