Anxiety :: Lack Of Sensation Or Numbness In Fingers

Recently I've been getting a strange sensation in my fingers that has moved to my toes a bit. I think it's mainly in my fingertips, like a lack of sensation or numbness that's very noticeable when I'm thinking about t like most symptoms. I have seen a few posts from people with these problems that have been counseled. Often my fingers and toes go quite cold too. Maybe it's the fight or flight process the body does when it thinks it's in danger? Or maybe it's the blood vessel restriction from the constant anxiety.
