Halppp..so nervous for doctor appointment

I have a physical soon, and I am getting really nervous. For one, I have White coat syndrome, in which my blood pressure goes high because Im so nervous. Even home monitors. Its just the act of seeing "what is ittt?" That gets me anxious. Then I was supposed to lose a bit of weight, but only lost like 5 pounds. Im just really anxious, that it will be a negative aura now, at this appointment. That I let the doc down somehow. How to ease worry around this??😟
