Oh man the what if's will kill you. Just set a date of when you will see her again and then forget it until then.
No point churning it all over every day until then, there is nothing you can do about it anyway other than torment yourself.
Between now and then just focus on you, get your heath under control, focus on eating and sleeping and keeping fit and then when you meet up, all your what if's will get answered.
If it's meant to happen it will, if it isn't it wont.
