When they ask what you're appointment is regarding:

Being greeted by the department receptionist:

The advisor asks: what happened with your grade in that class?

And they proceed to lecture you about the importance of a good GPA...

And tell you all steps you need to take to change majors/complete current major

And then you express to them you want to change majors or basically get anything done by the end of the semester

Essentially, advising meetings are one giant waste of time. Everything is available online, and they will probably give you poor advice 9/10 times. But unfortunately we all have times where we have mandatory advising meetings. Just stay strong, and you will get through it.
