I cant seem to quit my THC pen/weed addiction

I have been struggling with a thc pen/weed addiction and I honestly feel stuck. I have tried to stop multiple times, but I keep going back to it.
The hardest part is the cravings. Even when I genuinely want to quit, I find myself thinking about getting high, and eventually I give in. I have reached a point where Im frustrated with myself because I know I want to be done with this, but I cant seem to make it last. For anyone who has successfully quit THC, especially carts/pens, what actually worked for you? How did you deal with the cravings and the constant thoughts about getting high? Did you quit cold turkey or taper down?
