Getting them off the boob for good

Help lol It's been a year and a half... I think I've hit my limit. She's got so many teeth now (14) and 90% of the time she's not even seriously eating, she's playing with my nipple, on-off-on-off constantly. I feel like the water bottle in a hamster cage. But she has an absolute meltdown down when I try to deny her for too long. I try telling her no, it's not time for that right now, distracting her with other things like snacks, foods, milk or whatever. Sometimes it works, or works for a bit, and other times it doesn't work at all and she just gets more and more upset. I've kinda gotten her to only wake up/bedtime when I'm at work, but my days off it's back to the meltdowns throughout the day if I deny her. What has worked for you guys? Any tips or tricks? Is she just not ready yet and I need to suck it up??? I feel bad. But I also struggle sometimes feeling like I have zero bodily autonomy and am over stimulated. I can't even go to the bathroom or shower most of the time without her busting in, or if I actually close the door she's out there crying to be let in cause she can't see me. Mostly I don't mind, but some days it's just ... A lot. I'm getting sidetracked, though. Thank you in advance for any advice ❤️
