Hi and welcome!
I am sorry that you are suffering anxiety and its symptoms lately. It is easy to be frightened of these feeligs, caused by anxiety, and then get even more anxious....resulting in a cycle of fear and weird sensations throughout the body.
You are not alone in this experience. Many people have similar things that they feel when stressed. We have a great Resource Guide on the main page here (2nd post) that has a lot of great links to get you started with some self-help ideas.
The
breathing and relaxation exercises (instructions in links) are really effective in reducing anxiety symptoms if practiced daily.
Here is a link from the Resource Guide with a list of anxiety symptoms that you might find comforting. (you'll see yours listed)
