I'm 30 weeks pregnant an I still smoke a pack a day. I'm dealing with anxiety an depression an I can't quit. I do not have the will power. I can't believe it's this hard I'm so addicted. has anyone you known smoked this much while pregnant. my Dr said my baby is perfect. an Growing fine. he's always moving an Im healthy person no problems with my pregnancy. please don't judge me I know it's bad an it makes me feel so bad but I can't stop it just makes me more stressed an makes me smoke more when I start to worry.
