AITA for refusing to let my homeless mom live with me?

My mom and I have never had a stable relationship. During my teenage years she treated me horribly and it led to me self harming, hating myself and her. She always doubted my abilities and never cared about my education. Now she’s 54 and unable to work due to her body being too weak and people not wanting to employ her. She eventually lost money and her house, while I went on to start a business while working three jobs to support myself. I’ve now moved into a decent house with more than enough space for her and others. She suddenly showed up knocking at my door begging me to take her in. I said no and she started yelling at me so I shut the door in her face. I began to receive hateful messages from other family members for not taking her in, despite her abusive nature when i was younger and her lack of care for my education. I worked hard to get to where I am and i don’t need her negative energy around me. She’s now struggling and is in emergency accommodation but I have no motive to help her. AITAH?
