I agree with ellie about going in, to stabilize the situation.
I think, in part, you might be wanting to avoid seeing her because of a bit of embarrassment or whatever over how these big emotions came out of you, because of the texts you sent, and you sort of want to let more time pass between the outpouring of emotion and seeing her and dealing with them while the emotional imprint is still so fresh/raw/vivid?
I have had similar situations with friends, or even with my Ts on occasion, and my impulse was to not go face them because I felt too vulnerable ..... but I can say it has generally worked better to not let too much time pass before coming together and dealing with the situation/emotions together. There has been more peace and liberty and relief in having faced it, faced it together, come through it together, than to be still wondering and waiting, waiting and wondering how it will be ..... your separation anxiety might actually be eased by going, or worsened by not going.
You do actually have a few days, don't you, before your app't, to regain your sense of mental equilibrium? You may see by then that you feel differently about going than you do right now when this is still very fresh and you are still trying to catch your breath after the storm ..... let it rest, let yourself rest, let the decision wait a bit, perhaps...
