looking for support NOT criticism

So, yes I know it's SUPER not cool to smoke while pregnant. Or ever really, well. I've been smoking for roughly 5 years. I've been able to quit when needed (surgeries) and what not. Well I am finding it SUPER hard to quit now that I'm pregnant. I'm trying, trust me. I've cut back quit a bit, but I have days where I slip up more than others. I am extremely stressed with my life right now. Unplanned pregnancy, fired from job, buying a house, and being a young mom to be. I'm just over 19 weeks pregnant and would like to be done smoking completely by 20 weeks. My boyfriend is also a smoker. I've asked him to quit aswell, & he says he doesn't need too because he's not the one that is pregnant. When I was younger I would switch between pot and cigs. Well now obviously pot is completely cut off as I've never been addicted. I guess what I'm looking for is personal stories and tips and tricks to make this work for me. Thanks everyone in advance, & please do not be rude. I am very aware that my actions suck.
