Sinking, this is a good start, in getting more help. They're UK based, but are part of Help International.

As you'll see, there are chat rooms you can go into, support groups, self-help programmes, details of real life support, too.
I'm sure there will be an equivalent in your part of the world. Or stick with these people, for now. They have an email address, on the first page of their website. They really want people to contact them!
To be honest, this eating plan you've been told to stick to, with a desired weight goal at the end...
It doesn't sound great.
I don't mean to be negative about the advice you're getting from your medics. But that is the kind of thing the clueless therapists do.
Bear in mind, a T can never really admit they don't know what to do.
I really feel there is a huge variance in the quality of treatment for ED's.
I'm speaking from experience. The therapist I mentioned in my post above also gave me an eating plan. And... some foul and totally ineffective tablets to chew (they were supposed to swell up in my stomach and decrease my hunger). She absolutely had no idea how complex eating disorders are. She actually made me much worse. I felt that giving me these diet pills meant she agreed that I was repulsively overweight! As for the eating plan. I couldn't stick to it. And felt like a failure. But nobody can stick to a diet like that.
There are other ways, sinking!
You don't have to be hungry!
I really hope this gives you some options. And hope!
