Hi and welcome. Family is hard to live with, many here can relate. Can u write her a letter of the way u felt when she said those things? And give examples of what would feel more supportive to you? This way, you express the stuff as your feelings so she doesn't hopefully go too defensive. And this way you state what u need in a way she has time to think about it all. May as well try to make the relationship better. I suppose I deal with lack of support in real life by spending time here, maybe it will help u too.
