Am I too small?

I have struggled with Anorexia for the past 5 years. Because of bullying then financial instability. I am 5'6 and used to be 125 lbs. I lost a substantial amount of weight and last year I feel down to 100 lbs. I have really struggled to fix my eating habits and am now 115. I was so proud of myself and saw myself as being perfect. But my mother has been scolding me saying that I am too skinny. It really hurts my feelings because she doesnt know how hard i try everyday to eat more. Am I too small? I would serious like another opinion

?

Update: I have been really down on myself. I appreciate all the support 😢💙
