It sounds like you need a med change of some sort as you have had a hypomanic episode and are now depressed(did I read that right?). Do you have a therapist? Talking to someone would really help a lot too. I'm so sorry this awful illness has been throwing you around. Keep posting. We are here to support you. Stopping smoking suddenly may affect your mood either way. I have a cousin who goes hypo every time she tries to quit. Are you looking after yourself with diet, exercise, self-care etc? Are you safe?
