-hugs- I completely understand why you're frustrated with your friend. She really shouldn't be telling you to 'get over him' because no one's feelings, let alone yours, can change overnight. Nothing can force that kind of change.
Judging from the way she says 'whatever let's go' and 'who cares', I think your friend is tired of hearing about Tony and wants to change the subject whenever he pops up. Hopefully she will be a bit more compassionate in the future.
On top of that, though, there's something important that I want to tell you. You don't need her help. I know it's incredibly difficult to talk to Tony yourself. I know it seems impossible. But you honestly don't need your friend to do anything, and you'll be perfectly fine on your own. Don't let her hold you back, okay? Do what you want to do, when you want to do it.
