How to tell my significant other that 7oh isn’t kratom

I’ve been telling my wife that I’m taking Kratom extracts, but never really explained how 7oh is so different and the WDs can be crazy if I run out. I live in a state where it’s illegal so I can’t just go down to the smoke shop to get more if I run out. Online orders only. How do I tell my wife that I’ve gotten myself in too deep and I’m struggling? I’ve been spending too much money and I’m ready to quit but she thinks I’m just quitting kratom and it’s not a big deal at all.
