Hopping on mk due to eating inconsistency

So, im 16 around 182–4cm weighing at 63-5kg & for the better part of a year I’ve just been at a standstill weight unable to gain any due to a eating habit that i have where i eat super inconsistently. The routine goes like this; i eat like crazy for maybe 2–3 days then unable to eat much of anything for the rest of the week. & i believe that it stems from the fact that my mind is incredibly indecisive. In the days where i eat i have tons of determination to gain weight & “grow big & strong” 😭. But then after that i get really scared that im going to get fat so i practically starve myself & whenever i do try & eat more i just vomit it out. And to anyone who will say “do sport then you’ll get hungry”, at my peak i was doing 5/7 days doing sport whether that being badminton training, or weightlifting & i still had the same inconsistency. I’ve researched it & i would probably take 1.5g (500mg each meal or 1g (breakfast dinner)) of berberine to keep myself more insulin sensitive & i would start taking maybe 10 (0.16mg/kg) or 15mg (0.24mg/kg). IM NOT SEEKING MEDICAL GUIDANCE IM SIMPLY STATING MY DILEMMA AND WANTING ADVICE Though im open to ideas & welcome other possibilities

Also im scared that my growth plates will close due to the increase in igf-1 and im a bit scared i will damage my endocrine system permanently if i do this at a younger age
