Advice or personal struggles

I'm having a very rough day with my emotions... and my quitting smoking. I've been using the patch for a few weeks now, and today due to an argument with my husband I just snapped and bought some cigs and smoked 3. I've been smoking for 17 years, and it's terribly hard for me. I know I don't want to smoke, but I'm having a hard time with the urges. Anyone have any ideas? I've tried gum and snacks, been using the patch and it eliminates most of the urges but not all. I feel like I'm going crazy.
