Not a weight loss, but looking for friends

I'm not overweight, but rather I'm severely underweight. I know many would kill to be as thin as I am (I hear it every day), but in reality it isn't healthy and I feel terrible. I'm looking for friends and inspiration to gain weight the healthy way. I want to feel like I have more energy, have better skin, and be able to do my job and be on my feet all day without feeling wiped by the time those 8 hours end.
