I never aim to give someone sugar-coating. This is life, and it's not Disneyland.
The truth is, many people never "heal" from mental disorders. The only upside to them is that you heal as much of them as you are willing to battle. Someone fighting cancer, or a broken leg, say, is hindered by the process of physicality. They might yell, "heal, leg!" and wait for it to happen, but nothing bar natural healing will occur.
In our circumstance we feel the same is applicable but it's not. We have the ability to reason with, even barter with our diseases. An anorexic can give their disease "the day off", so to speak, with enough willpower.
But the serious matter of healing is that you must - and I mean, MUST - you must come to terms with your own ability to control your disease. Do not let it become an excuse - it is not a tag. Not a title. It is not a plague. It is merely a broken state of mind, a series of thoughts that tell you black is white. With enough reasoning, you can see that white is white, but may never see black is black. Does that make sense?
You understand wrong is wrong. But you might never accept right is right.
