Arya is so hard but what you did was very interesting. If you pair it with her being one of the few of her people trying to be active in the rebel cause and thus her not having in much help or being taught diplomatic skills. Her mistakes would be understandable because her culture was so different from theirs. For example elves value telling the truth because they speak in the ancient language so I could easily see Arya sticking her foot in her mouth and accidently offending people about subjects like religion, meat, and animal by products by telling them the truth. I could see her being really upset afterward because she hadn’t meant to offend them and feels like she under minded her cause.
