Do you think the migraines were caused by stress leading up to your appointment?
If they were perhaps you would think about telling your T this, by email or phone perhaps, before the one in two weeks.
I am sure at the moment you just want the awful pain and symptoms to go so I hope you can rest and sleep.
Big gentle hug Elsewhere.

You haven't failed, it is just your body reacting. Just get better soon.
