What's wrong beside me?

At the risk of sounding rude asking this question is a surplus of time unless you define what "chubby side" process. Are you really overweight or panicking nearly not being skinny plenty. If it's the former, it's stress. If it's the latter you need to see a doctor. The forcing of food down would put together me think that you enjoy a shrunken stomach which would indicate the beginnings of anorexia.
In which case I would these question:
1) Do you think you are monstrous?
2) Is there some issue that you cannot converse to about near another person?
3) Is near someone who is the object of affections who have been near a friend of yours?
4) Do you feel lonely and isolated?
5) Have you be abused?

If you feel any of the above question relate to you please feel free to contact me give or take a few it as I am qualified as a counsellor, and teacher, and psychiatrist.
