Is OTHER wrong in the post ? POST : (I’m on mobile so I’m sorry in advance)

My best friend Kat and I have been friends since kindergarten so we’re practically sisters. Recently I was diagnosed with a very rare form of brain cancer and while we caught it early enough doctors believe I’m a high risk for relapse in the future. Essentially I have been given 15 years max to live. Recently I held a WIG party where my hardiresser and close friends brought in wigs and shaved my head. This is where the problem starts. Kat has been sucked into one of those essential oil MLM’s and has become somewhat of a soul sucking banshee but despite all that she’s been supportive of me and she’s still my best friend. I’ve dealt with her saying her oils could do better for me than chemo and telling me I’m just killing myself faster by not using her oils so I’ve been close to my breaking point for awhile. I finally broke when Kat showed up without a wig or food but with a huge poster board of her MLM along with some of the products she sells. I of course started sobbing and all of our friends ripped Kat a new one. Kat has sent me some pretty nasty emails saying I’m not supportive and her mom has called my mom to scream about how ungrateful I am. I don’t know if it’s just my emotions being out of sorts or the anxiety of everything going on but I feel like a huge asshole.
