Just a suggestion - have you tried tapering your dose down? It is usually easier to stop a strongly formed dependency by gradually reducing the dose, instead of just stopping altogether.

Reduce daily intake by X% every week. If a given step down ends up being too painful you just go back to the previous one for another week and then try a smaller step next time. Optimum X varies by drug but I’m sure there are recommendations specific for cannabis out there.

It sounds like you have the desire to make a change, with persistence and the right technique you can definitely make it happen.
