Kitty, I hope you gain some weight.
I used to having an eating disorder 2 years ago when I wanted to be thin because I was chunky as a kid. I became very depressed because I wasn't getting proper nutrition. I was basically starving myself to death. I had to have an intervention. I was 5'8'' and I weighed 130 lbs. Now I am 5'8'' at 165 lbs and I feel better about myself. I realized that it is better to look like you're not starving.
I will do my best to reply with an educated, humble and honest answer. Ultimately, it is up to you whether you want to listen to my advice or ignore it completely. Sometimes, my advice may be wrong; occasionally, it will be right. Regardless, I want to do my best to give people answers they are seeking.
