A head circumference that's .4 inches smaller than normal doesn't seem to be outside the normal range, at least not very far. Also, at 17 you're not quite done growing yet. That won't happen until your early 20's. So you still have lots of time!
About cannabis, I personally wouldn't go there. Getting high can actually *cause* you problems, anxiety being just one. You should talk with your doctor, and perhaps ask about seeing a therapist. Self-medicating with illicit drugs is never a good idea.
I hope that helps!
