I tried gaining weight also,i ate tons of avacadoes,pumpkin seeds,almonds,walnuts,it still didn't work I was around 125lbs before going raw.Then after being raw i was 110lbs which is kinda weird for someone being 5'9 Floopy, sounds like the low energy you were suffering from could of been from excess fat consumption. Avocado is over 50% fat, and all nuts and seeds are over 50% fat. And fat is 9 calories per gram, where as carbs are 4 calories per gram. Do the maths, but I wouldn't be surprised if 50-60% of your daily calories were coming from fat, no wonder your body was going hay wire. Imagine eating a cooked diet with that much fat, you'd feel sick. Just my thoughts, dont mean to be rude. Mike
