Hi Rosie, I just wanted to say Please try and keep your chin up hun, It will work for you and really you are still very early days and not being able to go to the toilet won't help, Try taking somthing for that if your feeling bloated, I also think that your Not eating enough, I think you really do need to Up your protein, I know it must be hard because you say you don't like fish or meat, but Try some cheese, Beans, Nuts, Milky Coffees, Do You not even like shell fish? I have Prawns in shells everyday for my protein and sit with the box on my knee shelling them and eating them lol, I really enjoy my shell food and fish now.
I really hope your feel better soon, It will get better for you and you will lose the weight. My advise is to Eat More. (((Hugs)))
