Hi, I appreciate that you reached out with your concern.
yes, it would be good if you leave smoking completely but try quitting gradually.
Seek help from a therapist and consider treatment for your Bipolar 2 as well. Also I would suggest you to do Psychometric testing to help you identify co-morbidities. Tailored strategies to your specific needs with professional psychologist will help you.
Meanwhile, practice pranayam like Deep breathing, Candle blowing and mindfulness which will facilitate to quit smoking.
