The worst mom ever.

I stopped smoking over a year ago before I even found out I was pregnant with my daughter. She’s 4 months old now and I still don’t smoke and I breastfeed her. But I had a REALLY stressful week and I just smoked a few cigarettes today. I just came in the house after having one and I looked at my beautiful daughters face and just feel awful. I’m just crying and crying. How could I do this to her!? She deserves the BEST mom and I feel like the worst mom ever 😭😭😭
