Doctor's appointment today. Waste of time

So i was finally able to get to my doctor today. My appointment was for 145pm. I show up 30 minutes early. I sit in the waiting room until 215. They finally called me back. The nurse does her check up on me and asks why im here. I tell her about my issues with new tics, my headaches and my sleep issues. I also tell her about my er visit and the high heart rate and blood pressure. She looks at and nods. She leaves the room. Mind you my outbursts where pretty bad. Im stressed, tired, hungry and now running late. Not a good combo. She returns at 245 and says the doctor is running late and will be with me soon.
315pm. Still waiting to be seen. I have to pick the kids up by 415.
The doctor finally enters the room and says its best if i reschedule because hes running way behind. They weren't expecting me to have more then one health issues and next time inneed to request extra time so they can cover all my issues. I ask him if he can give me something to help me at least sleep. He says not without a full exam.
So why is it may fault. I got their early. I told them when i scheduled the appointment all my issues. He also asks me to leave because im making the nurses and patients uncomfortable yelling. But hey i don't have to pay my Co pay next time i go back. So theres that.
