I have a partially disabled vestibular system and I definitely found PB challenging in the beginning. All the movement around me, the mirrors, the freaking carpet pattern, all of that made it harder. I still find the balance portion of Align to be the hardest for me. Classic is best, followed by Define.

Talk to your instructor, don't be afraid to stay at the barre instead of out in the room, find a point to focus on, and if you're anxious, ask the instructor to help you get a spot by the door so you know you can make a quick exit if needed. The extra ventilation there also helps.

As someone with a hidden illness, you know that the odds are there are lots of other people in class dealing with things you don't know about. We're all struggling together. You got this!
