Bullying
So first of all I thought I should just take a dive into the deep end. Unfortunately, many people across England are being bullied then they can often feel isolated; this is totally normal. There are many different types of bulling whether that be verbal, physical, cyber. If you want to learn more about bullying then check out my bullying post.
Class time
I am sure that you have already realised this for yourself, but I have noticed that in ever class there is a class mate who thinks it is utterly hilarious to disrupt the class. If you are sat next to the disruptive person and they are trying to distract you then I would probably tell them to stop first. If that doesn't work then I would tell the teacher, they will give the student a warning. If all else fails then ask the teacher to move, a lot of the time they are very understanding and will let you move away from the person that is distracting you.
