How I ruined my Life(And my diet) in 30 mins.HELP!

I came home and just NEEDED a half cup of ice cream. I could fit it in my calories and figure di deserved a treat. I did that but then felt HORRIBLE. I had alreayd eaten today more than usual and tonight is my father's birthday and we will be going out to eat at an itlaian restaurant( bread and pasta galore). i felt so bad that i eat an oz. of cheese and some crackers and a twizzler. it's only 4:30 and i'm alreayd at 738 calories!!! i feel full and awful and in an hour i won't be full and we won't be eating for another 2, 2 1/2 hours. how will i restrain my hunger, especially sicne tonight i'll be eating more for dinner than usual?? I feel like i've ruin all my progress, my "start new and fresh and healthy" attitude.EVERYTHING. it feels like everyday i make a mistake and have to start over! i'm doing jm 30-day shred and i bike almsot everyday for 20 mins but those ar enot that much. i feel horrible!!!HELP!

You haven't ruined your life silly! It will be alright just calm down :) It's only one night, you can pick up where you left off with your healthy attitude tomorrow. I think that since it's your father's birthday you should just enjoy yourself...don't let this get you down to where you can't enjoy the night with your family. It's only one mistake, and you'll learn from it! The next time you want a treat like that just think about how you felt today, and it will hopefully keep you from that choosing an unhealthy snack. As for keeping yourself away from anything else before dinner time, try rinsing your mouth out with some mouth wash or brush your teeth. I know that I have a hard time eating right after that because my mouth feels so fresh and clean that I don't want to ruin it so quickly, hehe :) Please just calm down and enjoy your papa's birthday tonight!
