You did not post for help. You posted to vent or express your anger towards anyone that dares to offer advice. Most likely you are in the forum as a last resort as you have rejected all previous advice, you have pushed away everyone else with the excuse that no matter how good the advice it "doesn't work" because the people that offer it "don't understand". It's BS, but that is the excuse you tell yourself.
The excuse is understandable. It is a way for you to have or maintain just a little bit of control over other people. If you were to actually take care of yourself, if you were to admit that no one need "understand" to solve your problem, then you lose what little control you have over others.
It is really simple. If you had a friend refusing to drink water that asked for your help what advice would you provide? No matter how elegant you phrased your advice, the bottom line would be "drink water". If that friend replied, "You don't understand," what would you do? Nothing. That's right, you would do nothing more than repeat your advice because your friend would have set up a BS argument. Your friend would slowly lose strength, the entire time blaming other people for his or her situation, while a glass of water sat an arm's length away. The fact would remain you "understanding" your friend would not magically make your friend begin to drink water, because "understanding" would be at the sole discretion of the opinion of your friend. If you wanted your friend to live you would need to sing and dance and play 20 questions, trying to please your friend as they kept repeating, "you don't understand and that is why I do not drink".
Keep it up and certainly, your health will continue to decline and it will not be because people "don't understand". It would and will be 100% on you. No one is responsible for you not eating. You are responsible. No one needs to "understand you" before you choose to eat, not your fiancee, not any therapist, not some stranger in random forum.
