What do you do when a friend flakes on you?

So today me and a friend were supposed to go job hunting today. We had this planned for a little more than a week and she’s the one who asked me if I wanted to go.
Anyway, Our plan was for both of us to take the bus and meet up at the mall at 9:00am. I woke up at 5:40am this morning, took a shower, make-up, clothes, and got as pretty as I could get. It took me about 2½hours. Literally minutes after being DONE getting ready, she sends me a message saying she’s not feeling very good and wont be able to go. Keep in mind she was also up around the same time I was and it took her more than 2 HOURS to tell me she’s not feeling very good?.....So now I’m home, dressed to go out, and not doing anything…...................What would you do in this situation?
