Don't consider yourself a failure for not being able to quit. Most everyone who tries to quit isn't successful the first time. Sometimes it takes several times. I have two children also, and I've tried to quit since they were babies. It's a matter of will, and I was never strong enough to quit. I would make excuses. It's tough, but you have to quit making excuses to smoke and turn that around into excuses not to smoke. A lot of quitting is physical, but a lot is mental, too. If you can overcome the mental, you will be able to overcome the physical. My advice is to NEVER give up. No matter how hard it is and no matter how many times you have to try. Oh, and don't worry about the people around you--do this for YOU. You deserve to quit. I wish you all the luck and will power in the world!!!
