Getting 'stuck' can happen in therapy. My therapist said the same thing to me, that she felt stuck. But we eventually got through it. It doesn't always mean the therapist can't help you. But, I wasn't dealing with an eating disorder that was threatening my physical health.. perhaps you need to seek specialist treatment for that, as your T is advising. I too think your priority right now needs to be you. If you aren't healthy, I don't see that having IVF will do any good with things as they are - even if it takes (hit and miss for anyone), would you be able to carry a baby to term if you are in the hold of an eating disorder, and if as you say, your body is 'failing'? Why worry about IVF just now? You're still young.. and if you get healthy and aren't underweight perhaps you have more hope of conceiving naturally?

I hope you can get unstuck and conquer this, get healthy, and become the mother you want to be
