In my opinion, this song is about somebody who gave her all in her past relationship and did everything her partner asked of her because she genuinely thought that he loved her.
The line "But I know I am done, I've had enough" could mean that she has had enough of the way he has been treating her and she is getting out of the relationship.
"When you hit the ground, You'll be sorry that I'm not around" means that now she has left him, he will realise how good she really was and what she meant to him. But she won't be there to pick up the pieces this time, he has to face up to what he has done and where he went wrong.
"I don't know how to act or what to say
But I know I am good, I'll be okay"
This part could mean that he has taken all of her confidence but she knows that without him, she'll be fine and move on to something better.
