Is my mom doing the right thing?

i was 5'6 and 126 lbs, then i stopped eating junkfood and dessert so now i'm 112 lbs. she set up a doctor's appt for me, she's made me get 4 blood tests and an EKG (heart test) to make sure i'm still healthy, and she's sending me to a nutritionist/eating disorder therapist tomorrow. she wants me to go back to my doctor for routine weigh ins. i am extremely frustrated and angry at her and i feel like this is going to push me into having more eating issues. is she doing the right thing?? or should she back off? thank you!
