This obviously matters a great deal to you but it has also become quite clear that you have managed to become a thorn in their sides. You need to accept that this isn't going to go well, that the only result is increased frustration, disappointment, and perhaps even anger.

Some 'tough love here'...

Please, stop and consider all the energy you have wasted on this endeavour already. Is this what you wish to be remembered for? I say you need to move on and put this behind you. Better to invest your energy into something realistic that will bring you joy than to continue to go down this path to continued unhappiness. Finally, let us say you are successful... so what? What will the result be and how will it affect your life and further your cause? To what end is accomplishing this one task going to improve your life? No Peter, you need to step back and take a wider look at this. If you want to be appreciated there are other ways to achieve this.
