Have i eaten too much?

right so

for breakfast i had fennel tea with sugar and a piece of breaded chicken breast

i had a brownie with a chocolate cover (it said 150 cals on the wrapper)

for dinner i had several pieces of broccoli and 2 small potatoes, as well as a mini pizza (about the size of your palm), 2 mini pies (basically a mouthful each) and half a roast potato

throughout the day i had 2 unsweetened cups of tea and 5 pieces of gum

my target cals per day is 500, i can do less but not more, so have i stuck to less than 500? My cal calculator says I've done 1000 which is making me feel absolutely disgust?d at myself- i guess i just need your clarification?
