How to get 8 month old off my boob to sleep and eat!

I’m having so much trouble! This is my first baby. I have nursed her to sleep this whole time. A bad habit. She doesn’t take pacifier or bottle. She will not sleep without my boob.

My hubby and I want to go to an all-day event, but can’t go since baby needs me to sleep and eat. Im ready to get her off of me so that we can attend this event and finally have freedom! Freedom for me, and freedom for my baby. Any advice? How do I get her to take breast milk if she won’t take a bottle? Help!
