As someone that just finished their dissertation, I can certainly sympathize and I apologize for your situation. It's never fun when you're stuck in am awkward/tough situation with a coworker, boss, colleague, etc.
Overall, I agree with all the previous comments and while every situation is unique, I'll give my advice. And I'll say up front, my advisor and I got along fantastically; however, there were many of my colleagues that had issues with their advisors, so I can speak to their situations.
While we can always go to the internet to complain about the interactions we are having with people, it is important to remember that only 2 people's opinions really matter, you and your supervisor. Clearly the relationship has soured. And it sounds like you do not enjoy the work you have been given, and are potentially jealous of the work your colleagues have been given and the recognition or importance of their work, relative to yours. And it sounds like you'd like to switch to something more interesting, and with greater potential. However, it's important to remember that we shouldn't compare our work to others, and we rarely know the full story. And as I write this, I recognize the irony of that statement.
My advice would be to do something fun, clear your head. We rarely make rational decisions when our emotions get involved. And the voice you write in sounds like it is rooted in a soured relationship bent on trying to break the bridge entirely rather than repair it.
Once you're in the right head space, I would just ask to speak to your advisor. Often times we as people have difficulty seeing when people are struggling, if they don't directly voice their concerns, we would never know. Your advisor might not realize how you truly feel. Approach the situation with grace and acknowledge that the work needs to be done, but you aren't enjoying it. Then ask your supervisor if there are ways that you both can meet in the middle to make the project more enjoyable. Or propose if switching the work would be allowable.
Another thing to note, is its common for people to do an "assigned" project for the majority of their dissertation. I myself had two projects in the beginning that quickly became tiring and were not always what I wanted to do. But in hindsight, it helped build me as a researcher.
But there is a silver lining. It is often tradition at most institutions to allow you to, and more importantly, require you, to pitch your final project. Perhaps you could ask your supervisor if they could meet you in the middle. If you continue to work on the project they want, would they be open to letting you do something more directly aligned with your passions for the final project? Or if they want you to work on the current project, is there a way to blend the two ideas together? Or could your supervisor better describe why the work you are doing matters (beyond just, I have funding for it and it needs to be done). Sometimes just reminding people why their work matters is enough to instill a new found passion for it.
While I know these answers are likely not going to solve your problems, I hope that you take the advice to take a step back and approach the situation again and try to repair the bridge, before you destroy it entirely.
The world could use more kindness. I think if you approach it in a better head space and try to meet them halfway, you'd be surprised at what can happen.
Best of luck.
