Our parents have a special way of making us feel bad. I'm 33 and my mom especially knows the power she has over me. I personally think you're a great person and will try your absolute best to accommodate everyone.
Our older parents unfortunately cannot change their ways and will be set in it. I know family's very important, though our emotional well-being is extremely important as well. It's easier said than done, but do please try to realize that you're a great person and our parents are simply just who they are. I've come to accept this with my mom and try my best to keep things simple. Keeping things simple lets me feel at peace with myself while maintaining the level of relationship necessary to not feel guilty at the same time.
Big hugs your way
