I only watched a few minutes of it but judging from that and the comments, she doesn't seem so much crazy as emotional. She got married, had a family, and she feels her whole life is turned upside down. She is likely embarrassed in that she probably feels like everyone she knows saw a video of her husband cheating on her. Yes, her choice of husband seems poor, but most people choose unwisely when it comes to marriage. Especially if you are attractive and have alot of options. Being emotional and having the ability to record yourself to thousands is a bad combo.
IMO women have it tough in that they have a window of attractiveness and that window usually doesn't correspond to an age where they have wisdom and experience.
