Hello,
In your situation it sounds best to have someone else pick it up that has a valid government-issued photo ID. Such as a parent or guardian. Or you can have it shipped to your house.
This is taken from Apple's Website:
If you would like someone else to pick up your items, select Someone else will pick up these items. To pick up your items in an Apple Store, you will need to bring the order number and a valid government-issued photo ID. If you have designated an alternative pickup contact, they will need to bring the order number and a valid government-issued photo ID.
