I just had the worst day of my life, how do i cope with it?

so i'm a teen model in baltimore for magazines around the country and i woke up this morning to go to probably the best photo shoot i'll ever get to do - teen vogue's beauty section (the pictures get mailed to their offices). however i overslept. i was 2 hours late (my parents work on sundays and it is my job to wake myself up and drive myself to my work). i show up and am apologizing like crazy but they fire me. i understand them being mad, but i don't understand them firing me. THEN i go home and get on formspring and see people writing on this one girl's formspring. they are accusing her of hooking up with my boyfriend. i wasn't too worried but i just texted him asking him what it was about. he said "mads i'm so sorry i had a couple beers and we hooked up. can we talk before u do anything?" he came over and told me they had . i asked him if he felt bored with me and he said kind of and that it is intimidating being with me, which i don't even understand!! (someone please explain that to me) i said something like "well do you want to take a break or something?" and he said he wanted to break up to see what else is out there. so basically i got fired from my job AND dumped all in one day :( HOW do i deal with the worst day of my life, i am only 16 so i'm preeettty upset about this
