Nutrition Struggle-Help!

The nutrition part of recovery is one I really struggle with. Although I adore nourishing foods like nuts,muesli,oatcakes etc. it's the foods known as 'Treats' that I can't let by my lips. I would love to have an ice-cream, a chocolate bar( Toblerone or Snickers are my favourite),Cupcakes etc but I just can't bring myself to face them. It's a hurdle that just won't budge for me and I'm fed up. I don't mean to be so negative I just need some tips from others who had this problem too.
I think why I struggle with these foods is because of Body Image. I find I still struggle accepting my body and still fear the ''Blowing up'' or 'Ballooing Possibility,'' and it's just so silly. I really just don't know how I'm going to get passed this stage as it's been bugging me for so long so any tips please don't hesitate to share. I will be so grateful.
Also I was wondering if anybody had yummy recipes( breakfast/lunch/dinner/snacks)to share as I also find it abit hard to vary food seeing as I haven't really a clue about it!!

Hope to hear some tips and recipes.
Thank You :)
