Im not sure whether to invite my stepmom to my graduation?

shes been there for me since I was 3 so I see her as my real mom. But throughout my whole life...she made life hell for me. Im a forgiving person so I pretended it was okay until last year when I got diagnosed with depression and tried to commit suicide because of the things she had been doing to me. Now I feel terrible for having left and she tries to talk to me...and I've tried talkn with her but all she does is argue and yell and I dont want to hear it anymore. she has my two younger sisters with her..and I want them to go to my graduation because I still love them but I know she wont let them go unless she goes...is it worth it to invite her?
