Family stress?

okay well my gma just stayed the weekend with us, and slept in my room. i love her like my gma, but we dont ever talk. and my mom takes this as me being rude. and she just left today so my mom came into my room and screamed her head of to me and cussed and blah blah blah. well this happens everytime my gma leaves and im not really even doing anything. bc when i do try to talk to her, my mom tells me to leave or that im being rude. oh man my mom thinks i hate her and i dont at all ! i just dont know what to do. absolutly NOONE understands me this just sucks like no other and my mom wont even speak to me. uh idk?
