Bad mom

Me and my siblings have had a tough relationship with our mother for years. Everytime we try to talk to her about the things she does to us she doesn't even care to listen. She just yells and screams about how she works so hard to care for us on her own and blah blah. Her relationship with all of us is suffering and I wanted to try one last time to talk and get her to hear us out. But now I don't know if I should even bother. I feel like she knows to some extent she hasn't always been a good mom and that's why she won't let us talk about it. She's the type to figure out everyone else's family issues and give advice but pretends there's nothing wrong in her own home. I'm just sick of her toxic, nagging ways and I'm starting not to care if she has a strained relationship with her kids. I kinda think we would be better off trying to process and heal from all the years of hurt without her at this point. Idk if that's even possible? I don't want her completely out of my life but I also know she probably will never acknowledge the things she's done. It breaks my heart to see my siblings mentally and emotionally suffer like I did. Should we try one last time or just leave it and try to do therapy as a family without her involved?
