I had to get a job because college and I just feel like crap. My employer and colleagues are amazing, but I hate it because it's in sales and all I do is talk with people, and I feel so goddamn horrible. It's not like I can afford to quit it either, so I'm stuck here until September. My shift is in 20 minutes and I don't know if I can hold out for the next 8 hours when I'm already at the verge of breaking down. Help?
