Disclaimer: What I'm about to write is based solely on a sample size of 1 -- me -- so from a statistical viewpoint it's meaningless. I'm just gonna project for you now...

Therapy is the most important part for me, because the not eating is related to not feeling. The less I eat, the less I have to feel -- partly it's a smokescreen, something to focus on besides the rest of my life, and partly it's a way of externalizing my distress. The emotions are all internal, so I externalize it all by creating an internal void -- sucking down my emotions with hunger. Therapy is the place where I can work on accessing those emotions.

(heheheh -- it ain't working right now...)

I do hope that helps.

And best luck to you. Remember -- neither you nor your new filly are safe if you're in danger of passing out from weakness. Sometimes, I've been able to pull myself part way out of this by concentrating on what's best for my beasts. Maybe that can help you, too? (You wouldn't want to pass out on a horse, would you? It's not good for the horse, you know.)
