If i were tell therapist?

that I am 5'8 and 100lbs and that i sometimes go days without eating anything..and when i do eat i eat like a size of small one meal a day..can they force me into a hospital..because frankly i want to see a therapist for other issues..but i don't want that to happen..i quite happy with my weight and how i look.i don't see it as life threatening problem..i don't want help for a eating disorder..just for depression and etc..so should i be truthful with her or lie?? no rude comments..
