She canceled the link 4hours before the meetup

Texting since 2Weeks We really vibe, have phone calls and all that, today 4hours before our link she texted me

Heyyy, I just got up. Did you sleep well? I've just canceled my driving lesson. I've got the worst swallowing problems and a headache and I don't feel well at all. I don't know if it will get better during the day or not. Maybe we can postpone the meeting for now... and maybe you can still meet up with your friend. I'm really sorry because you've put so much effort into planning, but I'm really not feeling well.

Should I answer? If so what, or should i leave her on seen and fall back? Idk how to behave if I still should call her like we did last week and all that
