Sad songs and strong drink. Maybe you two stay in touch, maybe not. At least you aren't looking to impede her dreams, so I guess you can take some solace in that.
Sorry to hear you're in this situation, for what that's worth. Speaking of worth, try not to belittle yourself by thinking anyone is many times the person you are. Alittle humility is a good thing, but - well, I'm not one to lecture anyone honestly. You take care of yourself, from random stranger on the internet to another.
Sad songs.
Strong drink.
You'd be amazed what ordeals someone can survive with little more than that.
