Hi Joem and welcome,
There's "depersonalisation" and "derealisation" and I just call these things "feeling like a zombie"I never knew these terms when I first had bad anxiety in the early 90s but I sure experienced the symptoms.
What it is is being super self-conscious basically. With anxiety you are on high alert *all the time* and this does some weird things to you. It becomes a vicious cycle because then you panic about feeling weird and you feel even weirder!
So just keep in mind this is a common thing with anxiety/depression. It feels f'ing horrible but if you can just accept it you don't add more anxiety to it.
Are you on any meds? They can help a lot if you are at the point where it's hard to function.
All the best,
