Dian has a new job. She has to get up much earlier now than before - at 6:30. She finds this difficult because she isn't used to / doesn't get used to getting up so early.
I am wondering if there is any difference between those?
What is more, could you think if a situation where both the following phrases could be interchangeable?-- although I know almost the difference between their meanings.
to be used to
get used to
Any help would be greatly appreciated
