I hate to be a wet blanket, but you are going to hell because of what you did.
Haha, just kidding. Hey, one of the great things about vaping is that as you know, it's more enjoyable than ciggies. As you said, that one tasted like crap, right? I actually think it's good that you smoked it, just as a reminder of how much they suck.
You'd probably be doing more overall harm to yourself by fretting about smoking that .... than the actual smoking of it did. I like having the mindset that I can smoke one any time I want to (which I obviously can - still a relatively free country) - but I simply don't want to.
The old "finding a pack just sitting there" is a tough one, and I really don't think you'd have slipped if that hadn't happened. Prior to vaping, a lot of my quitting attempts involved pure dumb luck; if nothing insanely stressful, humiliating, or otherwise trigger-pulling occurred for a given time span, I could do OK - sometimes a month or two at a time. But there always seemed to come an event that made me say "that's it, I HAVE to have a cigarette, there is simply no question about it".
Of course, it's a totally different story now. Stressed? Have a vape. Humiliated? Have many vapes. Any flavor I want, any nic strength, any PV, any atomizer/tank/carto; maybe order some new flavors to cheer myself up.
I'd even say that the next time you find yourself desiring a cigarette for whatever reason, take one out of the freezer, set your microwave to "DEFROST" for about 15 seconds, and smoke the stupid thing. It will still suck. It will always suck. Cuz that's what ciggies do - they suck.
So vape on, please forgive yourself, and don't torment yourself with the thought that you can't smoke cigarettes any more. You can, but I really don't think you want to. I think you want to vape. Enjoy it, and have a vapalicious weekend

Good lord, I just read the rest of your first post. I had stopped right before you started to enumerate your recent woes.
You are a rock star. You're going through ALL THAT and you had one stupid ciggie because you accidentally found a pack? I'm not worthy; I bow to your superior inner fortitude, and will not disrespect you by even attempting to make eye contact with one so great. You are truly the Chosen One, and I tremble in your presence.
Seriously, ciggies don't stand a chance against you. Not a snowball's chance in the center of the sun. Magic 8-Ball says: "Your future looks ciggie-free".
I'm so sorry about your Aunt; I had to watch my mother take her last dying breaths several years ago, so I know what you went through. And best wishes to your Mom, and to your poor back, and to your expectant teenage granddaughter. Yikes.
Things will get better, and I know you'll do fine, Woman of Steel that you are. Take care.
