Hey man,
Sorry to hear about your situation. You sound like the type of guy she will not easily forget because you are very supporting and right for her.
But trust me when I say that people that have extreme anxiety live in a world of their own while they are going through hard times. For someone with anxiety issues, it is really really hard to let people help cos it is not something that people without anxiety can really understand. It is wierd. I try and tell my girlfriends and they are awesome and love to comfort me and they go out of their way to help me as best they know but from my perspective (having had anxiety issues for 14 years) it is not enough. It doesn't mean she feels any different about you. You have to understand that. When she levels out, she'll be back in your arms imediately i promise. Best thing you can do is try and let her know every now and then that you are waiting for her and that she can call you anytime if she needs you. But don't push her or desperately try and get close to her like you were without her making that move first. If you do, I bet she will repel you and it will make it worse. Please dont take this harshly, i am giving advice no threats. You sounds like a true gentleman and i hope she gets better right away and goes back to you as you were.
I bet she is very embarrassed and low right now, but only she can come through it. you can only wait. its not like a broken leg.
thats my advice. good luck i am sure it'll be ok. when she levels out let her talk about it and take it from there.
good luck my man.
