old class

Is it my fault that ive become like this? Or is it their fault for treating me like a dogshit for nothing? What did i even do? Did i deserve having my bag filled with their trash? Did i deserve being pushed alot? Did i deserve getting photographed without my permission? Did i deserve having a quiet voice because of them? I was so normal back when i was so much younger. I couldnt even tell my parents and teachers cuz i thought i will become a moron (i was already) i tried to not pay attention to them but it got worse and worse SO THIS ADVISE DOESNT WORK. My appearance was getting worse and worse and so my mental and physical health. I was taking too much meds so i ended up being in a hospital due to the fact that my hemoglobin dropped to 62 while the norm was 120-140. I was sick.
I think im more healthier but the fact is a fact. My voice is still quiet but im trying to get better. 
Im in different class now but there 2 people from my old class.( they still pick on me) I have yelled at them but they wont take my serious. They sometimes influence on other students to join their SpeCial trEatmEnt towards me, but thank god they are not really doing that. Except for some students. It just crushes my heart so i bawl my eyes out. 

I JUST DONT GET IT! Why me?? There more students who are quiet as me but they dont treat them as they treat me! WHY?? 

I started taking care of my face. i think its ugly because of them.
