Anxiety disorder

Any one else who suffers from anxiety disorders. Will you be back on your meds right after baby? How have you been doing without them during the pregnancy? I have bipolar disorder and anxiety disorder and I am pretty proud of myself actually that I'm doing so well! way more good days then bad. I am upset though because my OB thinks it will be better if I formula feed so I can go back on meds since I have higher risk of PPD even though I didn't get it with my daughter. Anyone else in that same situation?
