Is taking a day off of exercise okay? I feel guilty?

[Gabesky]

because I got called into work and so i couldn't go on my run at night as i usually do. Also for supper my family brought me home a bbq sandwich and there was nothing else to eat so I ate that. I still am sitting at about 1500 calories but I'm just worried about eating that and not being able to exercise and everything haha. I've been exercising for nearly 1 week and eating extremely well and have lost over 10 pounds so far, i just don't want that to hurt me for missing exercising and eating a bad dinner.
