Got bullied for the first time today, I feel like shit.

Got bullied for the first time today, I feel like shit. I've never been bullied in school before. I have normal friends, normal people in my school and they never mentioned anything about my stutter, but today it got mentioned on a couple of occasions and I really don't feel good. First, I and my classmates were waiting for food in the restaurant and this one guy came up and said like "G-g-g-give me an h-h-hamburger" and started looking at me. Everybody laughed. I kinda got over it and tried to forget it, but an hour later we were in the class and because I do all my exams on paper and not oral response, this one girl said "How can he do paper exams, and others have to do oral response" and it put my teacher in a really awkward situation and then after few seconds this one girl got up and said "Oh come on, he stutters, the whole school day would pass while he's talking" and it really got into me. I just picked up my bag and went back home and I don't think I will go to school anytime soon, whatever my parents say I would just not go. I don't know what happened. They never mentioned it before and we're going in the same class for two and a half years, and today it got mentioned a couple of times. I am really not feeling well right now in terms of my mind.
