Cancelling Interview for Health Concerm

small comp wants to fly me out to washignton and i had to reschedued because their first time I couldn’t do

Recently I’ve had unexpected eye issues (blurry vision) and although I can see. In order for me to read I have to be very close up to the monitor or piece of paper (like 2 inches away)

should i cancel and just let them know that i understand if this forfeits my opportunity with them at this time or should I brave through it? will charge me cancellation fees?

also they are allowing me to rent a car but if I do go I’m defintely not using the rental and will just uber/lyft around.

I also already have an opp and i was just interviewing with this company to see what they offer but tbh it seems like the universe is trying to tell me not to waste this company time...

Cur. TC 62k
Acc. Offer TC 70k
potential offer from what im told about company above flying me out 55k...
