Why am I not losing anymore???!?!?ugh

So i really put most of my blame on the fact that school has started and Im full time, and working part time. Although Its not a problem load wise, its not doing any good for my weight loss. I still workout faithful since thats my escape from a lot of stress, I am not eating the right things though. First off there is a Wendy's like 2 mins away from my school and second whenever Im stressed while studying I tend to snack ALOT..... which is not a good thing. So im trying to recondition my brain to eat only healthy snacks if I must at night time instead of cookies and all that other empty calorious crap. So today I must go shopping for lots of fruit fresh and dried, some whole wheat crackers, pita chips, and individual wrapped string cheese(Yum). Hopefully now that I have healthy options I wont have to reach for the wrong ones. I have plans for my weight loss and I cant let food hinder it.
