Whooooops I’m found out

So my wife just confronted me with a bunch of pills she found in my bag, painkillers and stims, which I have been using to get myself through the day after quitting kratom. I don’t have a prescription for either, just hustled it. I’ve been addicted to booze and speed before so this triggers all the wrong memories, she’s furious i have been sneaking around doing this. She doesn’t really know about kratom more than that it’s a silly tea I drink occasionally when I have a particularly rough day. She has no idea I’ve been addicted for a year and a half. She took all my stash. Looks like I’m forced to ride it all out completely straight edge and fix some marital issues along the way. Oh boy. Any advice?

Edit: thanks for all the great and supportive responses. I took your advice to heart and just told the whole story. And MAN was that underwhelming! She flipped out so much over the pills yesterday that I figured telling her about my underlying kratom addiction would be the last nail in my coffin but she just shrugged it off. And to think I have been afraid of telling her for so long! I don’t think she’s gonna be of much help and support though, she’s too sick of my shit and my inability to perform up to standard or help out like I should, but at least I don’t have to sneak around and lie anymore. Made it through day 1 (again) off of everything. It sucked. But there’s no turning back now. Thanks for all the support
