How is this diagnosed? I dont hear voices or see things that are not their but I have this constant feeling that I am not living in the reality. I feel like I am in a constant dream and that I am not real or part of this world. This was all brought on by anxiety about suffering frequent deja vu feelings and fear i have epilepsy and now it has gone worse I feel like I am not really alive anymore. Is this a sign of schizophrenia? if so can you treat irrational thoughts?
