It is possible that they would not try to force you...

But starving yourself can be life-threatening; I suppose you know that already.

Have you ever gotten in contact with BEAT? "beat is the working name of the Eating Disorders Association".

I had some information about a therapist named John Hevesi in London quite a few decades ago, but I am afraid that was too long ago for you. I think he possibly had some association with the organization that became part of BEAT. He would not have forced you to eat, and I think he understood a lot about the origins of eating disorders, and would know why forcing is not a good idea. I don't know if BEAT still would be of any help in that regard, though.
