Had no choice but to walk out

So I developed sciatica a few weeks ago and it's been excruciating. My doctor referred me to a physical therapist and my appointment was today. I was in a lot of pain when I walked in, and I went up to the desk and the receptionist looked at my insurance information and condensatingly informed me that since I had not met my almost $4,000 deductible, I would have to pay them a minimum of the $600, even though my insurance didn't require a copay. She said the minimum amount I had to pay today was $100. I didn't have that kind of money, so I had no choice but to walk out. So yeah, still in pain. Hopefully the YouTube videos and tennis balls will help. I literally can't wait till I turn 67 so I can get Medicare! I hate having to suffer because I can't afford to go to the doctor.
