Advice on tryingg to quit

I’ve been vaping everyday for the last three years. I started smoking cigarettes when I was 15 (I’m 23 now) and quit when I was 16. When I got with my now fiancée, I started vaping because he does too. We spend on average $400 a month on juice and upkeep on our mods. I’m absolutely sick of it. It doesn’t make me feel better when I’m stressed, it makes me feel worse. I want to quit so bad. I’ve tried to not make it a big deal, but the addiction worms its way in every single time to remind me that was my last hit, and I start panicking. It feels like I’ll never escape. Does anyone have any advice on how to combat these feelings? Thank you in advance!
