New here, girl trying to gain weight
My son is extremely under weight. The nutritionist has us calorie packing all of his food. For example adding peanut butter to his bread, a little cream to his milk (and no water). We still avoid sugary food and soda though.
The doctor also has him on a strict eating regiment. No snacking between meals so that he is hungry at meal time.
This is advice for a toddler, so the more I think about it you should probably go see a nutritionist if you are that rail thin.
Good luck with this and with school.
In the long run that ADHD medicine will slow down your metabolism. Watch.
I had the same issue with my ADHD medicine just try to eat as much as you can when you do eat and drink a lot of water cause the medicine ruins your appetite
