[EX Q]: Person1: Are you ok ? You seem a bit anxious .
Person2:Yeah , I'm OK , I have been having a lot of mood swings lately . I think it has to do with the pills my doctor prescribed that are causing chaos on my hormones .
Person1: So you mean you feel ecstatic one minute and then blue the next ?
Person2:Yeah , it's weird . For example just this morning I was feeling detached and lonely , even though there was really no reason to feel that way .
