My mother has a plethora of symptoms. She makes up fantastical stories- e.g claims to be a surgeon, spy etc. I don't know if she's genuinely delusional (i.e she believes them) or if she's using it as a defense mechanism (she makes stories when agitated). She gets anxious about a lot of minor things and wants things done in specific irrational ways. Attempts at reasoning often fail. She also avoids contact with friends and relatives preferring to be alone. Any diagnosis for these symptoms?
