I need help quitting smoking

Dreaming • Mumma bear to baby boy 🧸 and expecting again 🤰🏼 💕 Dreaming always dreaming 💕
Just found out I'm pregnant and I'm a smoker. I want to take care or myself and my baby. Has anyone quit smoking while pregnant? I'm really struggling with quitting, but I am cutting back. I try to be active and distract myself, which works pretty good but as soon as I'm relaxing I crave a cigarette. 
Im trying to not stress myself out. But it's stressing me out. Every time I have a smoke I feel horrible about it. 
If you've quit smoking or have any advice, please feel free to comment.
