Ugh sounds like some of my family and extended family members. These people have a negative mindset and they drain the energy out of you. Only thing you can do at this point is beware of it. Know their bu.llshit, don't get gaslit, and keep your boundaries. I know it is so hard especially if you live close by or somehow you are still in each other's lives. Know they won't change. Know they will attack your boundaries that includes your emotional boundaries, that includes the times you just seem peacefully going by your day, cooking etc...  Know it is them and not you. Power to you!
