how do i quit smoking

An

i just found out im pregnant and i know smoking weed is bad for my baby (so ive stopped) but its hard not to think about it and get more of an attitude when other people around me smoke. literally everyonee in my house (big family) smokes including my boyfriend so i smell it often. and please no one come for me saying i should love my unborn child enough to quit. when its not like that. ive been loving them since the BFP, which is why im trying to stop smoking but i was used to doing it everyday as a stress reliever now i dont have that idk what to do with myself. so i guess im looking for things to do to distract myself, coping skills for when im down and can't roll up. anyone who has any similar stories drop them in the comments
