Should I try to call my mother on Thanksgiving?

Should I try to call my mother on Thanksgiving? Some of you might remember that I had to place a PPO which is a personal protection order against my father for doing innappropriate behavior back in 2005 when I moved into my own place. I haven’t been getting along with my family at all since they think that I’m mentally challenged and so forth. Since I have a visual impairment and been blind since birth, they have a tendency to treat me differently then my siblings. I don’t know why that is though. Anyway, my mother and I seem to be nice to each other when I call her but then things start getting out of hand. If I end up calling her, would she appreciate me wishing her a happy Thanksgiving? or no? I don’t want her not to turn down my call since she did adopt me from China when I was 5 turning 6. Now that I’m 23 and living on my own, I’m dealing with certain situations the best I know how. My mother and I tried getting along while I lived with her but, she seems to favor one of my sisters over me. She doesn’t believe my father did any kind of behavior to me. I don’t blame her in a way since I’d feel that way if that were my husband. Which I’m not married right now. I miss my mother and would love to talk to her, then, I’m afraid her and I are going to yell at each other over the phone. She has been abbusive towards me when I was a child and also when I was a teenager. Should I tell this to my counselor as well? Or, should I just go ahead and call? I’m trying not to cause problems for myself. I just want to hear my mother’s voice. I know she treated me cruely but, I love her. Let me know your thoughts and opinions on this. Thanks
