Quitting smoking cold turkey

Please no judgement.. If you can't say anything nice just don't comment.. I'm 19 weeks and I smoke 5 to 7 cigs a day sometimes less depending on the day.. Every check up has been great.. Baby heart rate is where it should be and ultrasounds show development is good. I plan on just quiting and I have read that quitting smoking anytime during pregnancy is good to do.. I also read that cold turkey won't harm the baby.. I read this on many baby center sites but I was just wondering if anyone else quit cold turkey and if everything was ok by doing so.. I know how bad smoking is for you and for your developing baby and I'm so upset with myself for even choosing to smoke. I know how selfish it was and is so I just need positive comments because as most mothers who smoked know they have already judge themselves for this..
