Scared! What should I do?

To watch videos on YouTube that are over 18, you have to send your ID or credit card so that age verification can take place. Since I was fed up with this annoying pop-up and I'm over 18, I sent Google the front of my ID and am now waiting for the result.

However, I realized that I acted far too hastily and that sending this image to Google might not have been such a smart move. I've also read many times online that it's best not to do it… I feel extremely bad right now and am almost having a panic attack, afraid that something bad could happen… What could Google do with the data in the worst case scenario? I don't mind that they have a picture of me, but my signature, access number, and serial number were visible in the picture…

Have any of you made the same “mistake” and did anything worrying happen?
