Your family might need time to catch up to the new you. Give them a minute.

People update their picture of you slowly, and the ones who have known you longest update slowest. They are working from years of accumulated evidence, most of it accurate at the time. Their lag is not necessarily disrespect, though it can feel like it across a dinner table. Consistency is what changes their file, and consistency takes months.

Try not to argue them into the new version, since arguing rarely moves anyone. Just keep doing the thing and let the evidence pile up. If someone is still treating you like the old version in a year, that is a different conversation worth having calmly.
