On any new meds? How bad or frequent is your anxiety? Google derealization and depersonalization, these aren't disorders by themselves but sometimes accompany depression or anxiety if it's bad enough.
Yes, this sounds like derealization and depersonalization. Here is a definition from the go to medical dictionary, the Merck Manual: persistent or recurrent feelings of being detached (dissociated) from one’s body or mental processes, usually with a feeling of being an outside observer of one’s life (depersonalization), or of being detached from one's surroundings (derealization). Sounds about right, no? Treating anxiety often helps alleviate the symptom. Do you do anything for your anxiety?
