8 Weeks pregnant and a failure of getting off smoking?

im 20 years old and pregnant with my first baby. Ive smoked for 6 years and when i found out i was smoking i was smoking over a pack a day, Im now done to less than half a pack. It is very hard, and i feel the same way you do, i feel like a horrible mother and i feel guilty, but is so hard, I cant hardly stand myself sometimes, but i get cramps when i try to quit during withdrawls, it makes me nervous, i want to quit so bad but sometimes i feel like its impossible, people dont understand that do not smoke, but when smoking has been your stress relief for a long time, you dont know how to get away. I havent been to the dr yet, but i plan on talking about options with her. I wish you much luck, and remember that millions of babies are born healthy every day from smoking mothers, but there are the few that arent that lucky, hope we arent one of them. good bless.
