I'm 165 cm tall, weigh 56 kg.

I'm the ideal weight for my height now, but don't like my body and how it looks like!

I'd love to be skinny but I don't know how.

Fat tummy, belly, leg ..

I am, as you have probably noticed, very nervous about this. 

Any ideas?
 
I want to know what's wrong with me and how to get rid of this problem.
