Laura, mental health workers are constantly assessing you and looking for any sign of a mood disorder, especially if they know you aren't medicating. They are always on the overly safe side. I recommend that before going back on your meds, first tell the CPN (etc) that you are back on your meds. I bet they will say something along the lines of "you are better now".
Is there risk involved in you not taking your meds? I don't know. I'm not saying that I do, just giving an alternate opinion. It's such a buzz kill when every single person automatically says go on your meds, as if saying anything else would make them a bad person
