Hi,
Although I am no professional, it certainly sounds to me that you may by developing an eating disorder and the things you are talking about- only eating fruit and going onto thinspiration websites are certainly very dangerous!
I have spoken to many people who have eating disorders before and they all mention control and seem to have started this way- it is good that you are asking about this and asking for advice because now you are in a position where you can either let it take over you or stay in control and don't let the
ED take over your life.
Cutting back so you are only eating fruit is not heathy at all, you need nutrients from more than just this & it will probably just make you feel run down and even worse.
Why not go to a doctors and ask him to make you an eating and exercise plan so you can lose weight and stay healthy at the same time instead of damaging your body?
You can lose weight and still get to eat proper food.
As for your mother's comment- that wasnt right at all, she shouldn't knock your self esteem like that.
Please don't let this take over your life- stop it now!
Hope you make the right decision and things get easier for you soon. x
