Skinny fat female

I managed to lose weight and keep it off for the past 2 years.. I managed to lose 2 stone on this website and now I'm back. I'm in desperate need of help for my skinny fat situation. Can someone please help me with what I should be eating and drinking everyday or what's best to solve this problem? I don't want to lose any weight, just sort my skinny fat problem out. I'm so upset over this and I don't know what to do or who to turn to. I'm 20/f
