Should I go to my family's Thanksgiving?

So my family is having their own Thanksgiving celebration but Im not sure if I want to go anymore. I was on video chat with my sister and she saw my bong in the backround (she and my mom know I smoke) so for some reason she flipped out and told my mom and my mom called me and yelled at me, and told me how pot makes you lazy and then proceeded to call me lazy and threatened to cut off contact with me if I mentioned it again and basically just made me feel like shit. Both my Aunt and my grandma smoke for medical/nonmedical reasons and one doesn't even have a lisence. she never gives them this kind of shit I just don't know what the fuck to do
