Tell her: Yea I felt the same most of the time we all stressed in school. School is like a daycare to learn because our parents work for money to buy food and comfort. Stay strong focus and try to pay attention and it will be much easier and if you still need help that's what your parent's friends are for, and those fake friends bully's they are not perfect back at their home they could have problems or something worse they get hurt there and when they see someone kind and smart they try to make their life miserable. So don't let them get to you be strong stand up to yourself your smart talented and this is why god put you in this world he knew you would be amazing and strong. Your body is perfect everyone is perfect in their own way and remember that. We all love you!
Hope this helped love<3
