Hi,

sorry you're struggling with anxiety at such a young age. I have bouts of that and it will take you under if you let it. breathing and relaxation techniques help that. they have some Rxs for anxiety. Be careful not to overstate your symptoms to a doctor. they may try too hard and give you something too strong.

could you be hyperventilating. if so, keep a small, brown paper bag handy and try breathing into it when this anxiety/tingling episodes starts to happen.

You're too young not to get control of this problem.

about your neck, I check my pulse in the front. the muscles in the front of your neck would be scalenes. They're buggers to deal with. The back of your neck could be cervical spine problems. Although your nerves can cause autonomic changes in your body. Get control if you can.

Hope you find peace in your life.
