trying to get off vaping, myself, and it is both "not that hard" and... a very sticky habit. good for you. was never a smoker, but that doesn't make it a good habit.
I found the physical addiction much harder to kick. I switched to no-nicotine e-liquid and felt very little in the way of withdrawals. But months later I was still reaching for a phantom vape to puff on. It's been almost two years now and I never think about it anymore.
This might not work for your current lifestyle (if you need to be able to properly use your brain for any meaningful portion of the day), but an effective method, at least for people already using thc, is to replace the nicotine vape with a thc cartridge and essentially stupify yourself every time you think about vaping. And be cognizant of the anxiety etc, so that you continue despite it. Stick to that for a week or two and it works surprisingly well.
