Normal?

Is it normal for me (16 year old male) who has bad anxiety and lots of stress to have headaches every day for the past 3 weeks? And basically not feel the same ever since. I also just now feel depressed because I think there's something truly wrong with me. Can't really sleep at night anymore and feel very tired throughout the day. So is this normal? 

I’ve had shooting pains in my head every day now for over a week. Worried somethings wrong but apparently can be a symptom of anxiety 

Have you been to the docs? But sounds like the effects of lack of oxygen to the brain through you’re anxiety, do breathing exercises to get the oxygen flowing to your brain properly, I have a technique I was taught if you would like it. 

That's not good hope you feel better. And yes probably is a symptom of anxiety 

Yes I have been tic the docs and he said it's also anxiety. Lack of oxygen to the brain? How so? And yes I'd love to know the technique.
