That's pretty routine for specialists these days if they've got a good reputation. Some really good doctors affiliated with good hospitals in NYC are 3-5+ months out for new patients. A lot of doctors only see new patients 1 or 2 days a week during certain hours. It's even worse when they also teach or do procedures, since they've got only so many office hours. They pick and choose based on severity/urgency who gets those slots and what order.

Some will just decline you unless you've been to another specialist already and that didn't go well. I had one who asked for some tests to be faxed over, then the office told me they could see me in 2 months based on the doctor glancing over the tests. [Shrug].

After that first appointment though, you're in and scheduling follow ups or even a new appointment for a new issue with that doctor becomes 100X easier. It's just about getting in.

I wasn't really symptomatic, but like many, many, many people living in this part of the world, I was Vitamin D deficient. I actually asked for a test after a coworker telling me about their deficiency. My doctor just added it to the blood work I was already having.

I did find after taking supplements for a while I was less lethargic in the late afternoon, especially in the winter months. I guess it was my "normal" for years (or always, not sure if deficiency is common in kids or not?) so I never noticed it, but after being on supplements for several months I realized something had changed. So I could totally believe deficiency could be a cause of your symptoms. The list of possible symptoms is huge and diverse.
