Reading at meals is considered rude in polite society, but if you expect to succeed as a writer, rudeness should be the second-to-least of your concerns. The least of all should be polite society and what it expects.
If you wrote something for which someone sent you a check, if you cashed the check and it didn't bounce, and if you then paid the light bill with the money, I consider you talented.
My first feeling was that there was no way to continue. Writing isn't like math;in math, two plus two always equals four no matter what your mood is like. With writing, the way you feel changes everything.
