Molly Is Huge! :( Not Pregnant.

My molly has gotten huge, at first I thought she was pregnant but it's obvious now that she is not.
Does anybody know what is going on and how I can help her?! 
 
Thanks.
 

Doesnt look good, extreme form of dropsy maybe but I don't think so. She looks very bloated as if she has been blown up. Is she at the surface all the time? I don't know much about fish bloat (I just looked it up) but that could be the answer.

I found this.

This could indicate anything..... Are there any other symptoms? what does her poo look like? is it white and stringy? is she acting out of the norm?
how long has the tank been set up for? how have you cycled it? what are your water parameters? other tank mates? how long have you had the fish for?

Try feeding her peas, and +1 to everyone else.
