I am a 30 year old female. I was about
your age when I encountered my first onset of anxiety.. It was a terrible time in my life!
Since then, I have had panic/anxiety on and off. Here is one good tip for you. I have been dizzy, tingly, numbness everywhere, shaking, nausea, hyperventilating, heart palpatations, thought I had a lump in my throat, no appetite, flu feeling, JUST TO NAME A FEW. and guess what? I am still here, alive and kicking!!! So don't let your nerves get the best of ya!
These feelings you are having are very scary but will not hurt you in any way.
Hope this helps, and always remember, anxiety will not hurt you
