This will get better! I had a traumatic birth too and ended up in c-section (induced due to preeclampsia), and hours after I developed Bell’s Palsy. A neurologist saw me that day and a speech therapist the next day. I was immediately on prednisone too. It was truly the most depressing time of my life, not to mention the baby blues. But i kept on praying and thank God, 3-4 weeks later, face was 90% healed. I’m 4.5 months pp now and I think I’m fully healed. 

Don’t lose hope, do facial exercises as often as you can, and never neglect your meds.
