R91 you are just in denial. Its a defense mechanism. Look it up on wikipedia and understand how it works.
In brief though here is my version for the moment.
Denial is a defense mechanism of wanting the problem just go away by itself, without you having to do anything at all. Its a refusal to accept that there is a problem. Its the inability to recognise the seriousness of the problem and to realise that the only thing to do is to get off your bum and take action because it will not go away by itself.
Its a shutting down mechanism. Meanwhile you anxiety is likely to rise because deep down you know there is a problem. Your anxiety will cause you lots of immediate pain. And your overall problems will increase.
I hope you can break through and not continue in denial. I hope you will work cooperatively with your therapists. But if you decide not to, then when other problems come to the surface eg depression or anxiety, i hope you know what you have to do in order to resolve those problems - eg tackle the eating disorder.
I wish you all the best.
