You can do it! I hope the AD takes the edge off. Sounds like you had a great trip, though. Deep breathing really helps. When I'm anxious, I forget to breathe correctly and the lack of oxygen flow really messes up my head. Take time out to "ground" yourself and affirm that all is well & safe in your world. Mentally visualize yourself displaying calm, serenity--lol! a mental photo-journal.
Oh, one note: I love your microwave spaghetti squash recipe/idea. Too easy, effortless & yummy! Very safe.
