Should I go up to the full 120 lbs?

a year and a half ago I joined an anorexia recovery group. I was 5'5" and 80 pounds. the doctor in the group told me I should be 120 pounds. I currently weigh 110 pounds and I'm not part of the group anymore, but I check in with the doctor once a week. she's still pushing me to gain the last 10 pounds. however, all my friends and family say I look great now, better than ever, and guys are starting to notice me and make nice comments about my body. should I listen to the doctor or stay the weight I am?
