You poor dear. It makes me so sad to hear that you are going through this too. I have times where my mind tells e it's not worth the effort (usually it's tells me that the pleasure from food is so temporary, but the thinness can last forever). And if your so thin it makes you weak, it is definitely a problem in your life. Do you have a therapist? A good therapist (if one has the insurance to cover it, of course) is an invaluable tool in dealing not only with ED, but all of life's stressors. The scary thing about EDs is that they are like addictions. They start out mild and before you know it they have taken over your life.
Virtual hugz to you.
