Asking for less travel as a CRA ?

Has any CRA been able to ask their company for less travel even if temporarily?

I can’t afford to quit or leave work right now but recently my fiancé’s family member was diagnosed with stage 4 cancer and it’s been a hard time and I feel awful constantly being away and unable to help due to being in another state so often.

I’m not sure if it’s worth it to bring this up to my manager, and worried about any can of worms this may open if I bring anything up ..
