I would never try to take anyone's choice away from them..... as I have always felt very strongly about my own right to choices...

I also hear a great deal of pain in your post.... the pain I believe is there for all of us with an ED...so I don't know your "exact" pain... no... but I know pain... and anger... too...

We are all here to support you... and listen......

My own ED... has been full of struggle... and pain... and has damaged my body... that I cannot reverse.. I wish I could... but it is there with me...

I will say... that telling your T... will not make her "stop" your behavior... you would perhaps get some much needed support....
as the only one that can "stop" an ED... is ourselves... and that is the truth...
