Cutting family off

I am getting very frustrated with my grandma, and each day think more and more about cutting her out. Its been 10.5 weeks since loosing my fiance at 36... I am fucki g trying the best I can and it isnt good enough for her. Tonight she belittled me and yelled at me for not having it together and she said she's sick of seeing me suffer. I am so fucking angry , I am trying. I was drinking every single day and have managed to get my drinking down to 3x a week now. I go to AA , I go to therapy , I see a nurse regularly, I have a phyciatrist. I am fucki g trying !!! Sorry it's a little hard when I have to carry around this debilitating pain every day. I am so fucking tired of people getting mad with me or something when they haven't been through this. I am so frustrated.
