Still no Improvement on Gain Weight Plan

I met a long time no see friend in a restaurant yesterday. The first word came out from her is: Why you so slim one?

Honestly speaking, this is the word that I hate. I have try all my hard and best way to gain weight but still not even gain one kg. Yes, I just check and confirm that I weight is still hanging at the same point. I am so afraid that my weight goes down again. I fully aware the dangerous of my weak body weight loss. I don't want back to my life staying in hospital.

I am wondering is it because of my stressful working life make me failed in gain weight plan. If so, that's mean tension and pressure lifestyle is more powerful than diet pills. I hate this fact!
