@kevin notvapelord , I hope you get your situation sorted out. Maybe if you can't go in, you can call the vape store instead, and talk about the problem and arrange a time to meet, if you are anxious around people.
It sounds like you've enjoyed vaping, and you can certainly get a cloud chasing setup that is safer than a mech.
You could also (as you say, "My parents are gonna be so ...... at me." Possibly enlist your parents help with the vape shop? They might be able to go in with you and help you with your bank if that's hard? They also might be willing to pay for a vape for you rather than having you return to smoking.
If my kid came to me in such a situation, I would help him out (both with returning the mech and replacing the vape, if needed. I mean... He's my kid.)
Fortunately enough, my kid is savvy enough to research vaping, although I think he uses another forum. For a long time he was correcting MY vaping rather than the reverse.
However, it looks like you've seen that you need to do some research both to vape safely and to learn more about vaping safety, and that is the GOOD PART.
Keep your eye on THAT PART, although I'm sure you are feeling upset at the moment, but you've learned the hard way, and without damage to yourself or anyone else, and that is also the SILVER LINING in this.
Stick around and keep learning, we all want to help.

I know this second sucks, but things could have been WAY worse. Seriously.
