I wasnt bought up to ask for help. It was beaten in to me by parents and teachers, to work things out myself, today that causes me significant cognitive dissonance which is legal torture and a way to make people self destruct.
Besides why should other people know how I'm being done over?

And now you have to learn the counter-lesson the hard way. Doing things without help was not beaten in to me, but through formative experiences and temperament that's also my default. It's a difficult habit to break, but the most powerful people do break it (or never had it in the first place).
One of the explicit duties of the police is to record and, if possible, to respond to civil and criminal infractions. A hit-and-run, or even a plain hit-and-stay is such an infraction. There's absolutely nothing wrong, and plenty of things right, with informing the appropriate people of an incident for which they have a duty to respond.
It's advice, not a lecture. You seem to be extraordinarily cynical and conditioned based on your life experience so I won't try to give you any more advice based on my life experience.
