There is a word that is slipping my mind. It is a medical symptom and it's a general feeling of unease. It's a term used by doctors for that feeling of dread/restlessness/"something is not right" thing. It's not a panic attack or anxiety. It's also not disphoria. It's on the tip of my tongue but I can't remember the term, can anyone help me out? I think it starts with an- or something like that but not 100% on it.
