I'm glad your new center and neph are working out well for you. how do they plan to work on your needle phobia? Sounds complicated, but hopefully they've had success in the past with others who have the same problem. Let us know how this progresses. Waking up on the floor sounds scary - I hope you were not injured when you fell.
I had a few of those low blood pressure falls. Hate those. Each time I bent my glasses badly. Try to remember how you felt right before so you can learn when to sit down.I'm glad your new center is working out. Good luck with the phobia thing. It will probably take months but it will be worth it.
