Don't be disappointed - you did what you needed to do. And now you have plenty of time to focus on your physio, getting stronger, and kicking butt in the summer. There's no point beating yourself up about it.
Congratulations! You made the team. Now concentrate on getting healthy! Best wishes!
Great that you could actually run in the trials even you were far from your best abilities.
The "miracle" was maybe the close call to make the team at all - but that´s what tie-breakers are for. Don´t feel bad though - you definitely deserve your spot.
Now time to get better and back into your usual shape :)
