Relapsed

To preface I quit vaping just over a year ago (know it's just nicotine but it's technically still an addiction and I just need advice). I started up again like a fucking idiot and now I'm hooked I think. I've only been vaping again for about a week thinking I could handle just doing it at work (stupid idea) but now I feel like doing it all the time. I successfully quit with chantix before and am starting that again. I'm not very proud of myself. Is there any advice to give on what else I could do? I don't want to tell my doctor I relapsed and have him think bad of me or not trust me since technically it's an addiction.
