My co-worker mistakenly believes that she is not deathly boring. Should I apologize for telling her the truth?

She stopped by my desk yesterday and wouldn’t stop talking and I’m too nice so I didn’t ask her to leave me alone but I got so upset that she wouldn’t stop telling me all her stupid problems that it made me cry and when she asked me why I was crying I told her the truth that it was because she wouldn’t shut up and leave me alone and then she got really mad and yelled at me saying she thought that we were friends but how can we be friends, I asked, when you never listen to me you just tell me all your stupid problems with your miserable, pathetic life, your husband who drinks and your ugly and untalented kids and your bezatch of a mother-in-law and you don’t know anything about me (which she doesn’t, I’m not making that up) but she was too mad to listen so she just went on about how it wasn’t fair that I was treating her like that when her life was so hard so I said there you go again, perfect example, you’re still not listening to me and you talk so much it’s enough to make even a psychotherapist hate you for oversharing and now she won’t speak to me and then she found out that no one else in our office likes her either and she’s blaming ME for it as though I were the relentlessly self-centered one who can’t stop talking so my question is should I apologize for telling her the truth that she’s intolerable or just hope that she quits?
