Caring for adult child with mental health disorder

My daughter is 25 and lives at home with me only.
The last 12 months she has suffered from severe anixety and depression, diagnosed with adhd, She had history of self harm and attempted suicide. She has been hospitalised twice this year. she has been out of hospital for 11 weeks and now paces for 12 hours a day, will not leave the house and now refusing to engage in her mental health appointments including therapy. This has had a significant impact on my life, well being, job, financial security. i feel like a prisoner in my own home. I don't recognise who she is or who i am. people say i need to prioritise me but I'm not sure how i do that without guilt and feeling like I'm abandoning my mom duty of care. Just looking for some other peoples views or experiences. The impact of her health has impacted far beyond me too, my sister, her friendship group, my elderly dad too
