Honest advice needed please!

I rarely post here but I really need some outsider advice. Sorry if the story is confusing or if there are any errors. I’m super upset and I cut some things out to make the story shorter.

                I have had plenty problems with my family, especially my parents in the past so I distanced myself from them for the past few years but recently my mom and I have tried to repair our relationship. I knew this was going to be difficult but I already feel myself wanting to give up.  The first few weeks we started talking to each other everything seemed fine. We made it a point to hang out with each other at least once a week and I visited her plenty of times. I was even cordial with my father and sister who I have extreme problems with.             

                Now things are getting very difficult. I went to visit her a few days ago and we go into a small argument while I was making her dinner. It started to get very heated so she went into another room to cool off. Then, my father gets involved and starts screaming at me saying how he regrets the fact that he stopped beating me when I was younger and how he was going to slap the sh*t out of me for being such a nuisance and messing up his life.  After that I left crying.

I didn’t speak to my mom until yesterday. As soon as I saw her she began saying how it’s my fault everyone is mad because of how emotionally detached I am from them. When I told her what my father said, her excuse was “He was just defending his wife because you hurt her feelings”. When I told her that he also said foul things about her that day her excuse was “he just says and does those things out of anger”.  After she said that I listed things she let him do to me “out of anger” and asked if she thought her husband was worth sacrificing one of her daughters and she had no answer.

Today she was trying to act nice to me. She kept wanting to talk like nothing happened and I just gave up and pretended like everything was okay to avoid conflict. Do you guys think that I am wasting my time trying to repair my relationship with her? Do you think it’s possible to even have a decent relationship with her and not my father? Am I overreacting or do I have a decent enough reason to give up?
