You need to start fixing
yourself first, then worry about the bolt. You may think I am joking but I am not. I have many issues that I would have a hard time getting through life if not for the many self help books I have read over the years.
Get this one to begin.

Yesterday I broke a bolt off too, in a 2016 HINO truck that we have been working on at the shop for a few months and we REALLY need to finish it up. I broke a bolt off holding the mirror to the door. I looked it over finding a solution, drilled the thing out, ran a tap into the bracket right there on the newly painted brand new door, ran a new bolt and moved on.
There is no reason what so ever to be so upset as you did, it helps nothing and only creates more problems.
It's always best to run a tap through threads like that. If you are working regularly on cars I would highly recommend getting yourself a nice tap and die set. Remember that the taps are hardened steel and break easy so don't ever force it, you go in and out a fraction of a turn to use it. With each turn going in a little more, that's how you basically use a tap.
On your hood, one thing you need to do is to be sure you don't drill a hole through the bolt into the outer sheet metal!
I solve this usually by limiting the length of the drill, put a piece of tubing over it if you need so the drill can only go as deep as you want.
God luck, and honestly, get yourself this book and start a life of study, there is no reason not to. I am very thankful for the books I have read that help me every day.
