I '36M' am thinking of cutting all ties with family members '36M '

I '36M' grew up in a very unstable home. My parents constantly demeaned me and called me useless. I was never really that close to my siblings and have never had any sort of deep connection with them, but they all seem to think I am stupid and weird. I called home for mother's day and they said I looked like I had gotten fatter and then told me to not get scammed abroad because I am stupid and naive. Whenever I mentioned to my family about goals I had they would say things like: "You? Forget it. It's impossible for you". In my 36 years of existence I have never once heard a word of support from any of my family members. I am pretty tired of this and at this point I would be okay with cutting all ties or at most texting with them once a year. Ideally it would be best if they would never want to contact me too. I am thinking of asking them for a ridiculous amount of money (with no intention to receive anything of course) and just be very annoying about it with them so they think I'm a leech and would want to avoid me of their own volition. I am trying to think of the best ways to make it so that they would cut themselves off from me forever and never want to contact me again. What is the best way to achieve this?

TLDR: Family doesn't respect me and never supported me. Want to cut all ties and what is the best way to go about this?
