It's normal to still crave a cigarette at your stage. There are other substances in cigarette smoke besides nicotine you're addicted to. The good news is, that'll pass relatively quickly.
Most people don't quit immediately. Some are able to once they get a match of equipment and juice that suits them. Others slowly ween themselves off the old and replace it with the new.
Keep in mind that vaping doesn't transfer nicotine as quickly to your blood steam/brain as smoking does. So before you break down and light one up, try vaping for another 10-15 minutes. If the urge is still there, there's no shame in lighting up for now. But purposefully try to vape more often than you smoke, and increase that ratio little by little until you maybe only have one cigarette per day. Then maybe one cigarette on a Friday night. Then none.
Or...
realize that some psychological withdrawal is normal, and a little physical withdrawal from the non-nicotine substances. Fight through it. In 10 days or so, you'll be in the clear physically. Psychologically, you will still miss smoking a little bit. But that will fade more and more over time.
After a few weeks of only vaping, something really cool happens: Your sense of smell returns. Suddenly, you'll smell just how much cigarette smoke actually REEKS. It's all down hill from there.
