This is pretty personal but I do need advice?

I became anorexic about a year and a half ago and, of course, had all these obsessive, stressful thoughts about food all the time. I've gained the weight back and now I'm fine...physically. Mentally, however, I'm not fully healed. I still pick at my food little by little and pretend I dropped it on the floor or something to avoid the calories. I feel bad for eating a little too much cheese...today, for example, I had a burrito from Taco Bell and I feel like I should've taken out some of the cheese to avoid all the fat. I eat only half a scoop of oatmeal for breakfast with a banana. Little things like that all the time. If I ate too much of one thing, I start skimping on fruits even. I need advice on how to get over this. How do I stop feeling bad about the cheese today? My parents still watch my eating and I think the number one reason I didn't remove any of the cheese today was because I was afraid they'd ask about it and I'd have to lie to them. Now I feel like I should've lied!
