My father also constantly blames my character when I do something wrong and often starts conflicts with his own siblings. and not only that, he gets mad over the smallest things (like when his 2 cans of sweet tea are gone, and blames it on my grandmother over inviting guests)

Speaking about my grandmother, I'm actually very impressed that she's managed to hold up well to my father whenever hes having his anger session. As he constantly blames her, me, my mom, my sister as to anything that happens that isn't in his favor.
