Oh and she taken the test so no going back now:(
As you said, nina, there is no going back. Just look forward now . I can feel your sheer disappointment for your daughter as she has very high hopes.
But you can only now be strong for her. Wipe your tears and make sure you are there when she comes home from school with a big smile on your face. You don't have to talk much about it anymore as it's done. But come nearer the time, you can gently bring up all your other thoughts and put it to her what other options might come into play.
You can prepare yourself and then her later on. It is us parents who have to go through all this for our children when and if they suffer any kind of disappointment or hurt.
You can always come back here for moral support and also if you do have to go the other routes and she doesn't make the pass, there are good people here who will guide you.
Hope you have a well deserved treat yourself as you have worried so much for her.
