I'm a new poster here, just trying to piece together my thoughts. I've been following Tiffany's story for awhile, I found her just after she announced her diagnosis. For awhile, I found her sweet and charming, and I felt so sad and sorry for her that she was dealt such a tragic hand in life. I honestly thought she was much younger than she actually is, based on her relationship with Amma, like early 20s. After awhile, it began to felt like her sweet disposition had to be an act, or at least partially so. I was shocked to learn that she had been an optometrist living on her own before all of this. She just comes across as so childlike and immature. I also think she's starting to show her true colors with asking her followers to tattle on each other - tick tick tick. She's also so clearly capitalizing on her diagnosis as a route to YouTube fame. She had a channel for years before this, and as others have pointed out, she tried to gain traction with makeup and lifestyle content, mukbangs, etc. She finally has something to offer that people seem to be interested in, so she's dragging it out as much as possible with click-baity tags, merch, catchphrases, etc. I don't agree that she should get off YouTube, as I think if she did, she would settle into a deep depression that she probably wouldn't be able to drag herself out of.
As far as her relationship with Matt, I think she's much more insecure about it than she would like us to know. There was the time at the train station when she watched to make sure he was going where he said he was going, if I'm remembering correctly. And more recently, he was going on a bike ride, and you can see in her face that she's worried about if he's really going where he says he is. I 100% agree that she thinks about how having surgery would affect their relationship, and whether he would stay. As awful as what she's going through is, it must be just as hard to think that your partner might not be there for you if you do what's necessary to save your life. Matt was also very quick to jump on the WW train, whereas someone who wanted to make sure Tiffany would survive would have advocated for the opposite. I feel the most sympathy for Amma, who is clearly well aware of what is most likely going to happen, and is devastated. Unfortunately, Tiffany is so wrapped up in her magical thinking about the curative power of prayers and well wishes that she's unlikely to accept reality. I also agree with those who have suggested that the doctor is suggesting WW based on the likelihood that the surgery would actually cure her is next to nothing. I believe it's already spread to the lungs, and the surgery could perhaps give her more time, but she may not be strong enough to get through it, especially after her severe reaction to the biopsies. Her quality of life would be significantly less as well. Tiffany is so wrapped up in appearances that I can't imagine she would sign up for colostomy and urostomy bags even if it would save her life. I can't imagine that her quality of life now is great, either. She seems very poorly a lot of the time, she looks like she's struggling to walk at times, etc. I'm glad to have found this forum of people. I couldn't believe that the commenters on her videos represented what everyone watching was thinking.
