Today was my first appointment with a new therapist but I left his office in 1st minute because i was too hot?

You know, I've found that buildings are raising the temperatures to save money. Even a 2 degree change to 74 from 72 can make it more uncomfortable. And not only that but there is less air moving through the building. And my experience is that it feels suffocating. I don't think you were wrong. I worked for a company and protested that I wasn't getting enough air and just kept complaining until they adjusted it. Talk to the doctor and tell him how you physically felt and see if he can do something - if not, ask him for a referral to another doctor - tell him you can't do it.
