Answer:
A class can negatively affect my future hy getting bullied so much till you self harm or try to get yourself out of school by committing. Which is not okay !! Many people can go to the point of killing others as well. Another example is by making you concentrate on them and not your work, you could block all that out by putting some calm music in your earphones and getting your classes up, if you think it's too late because it's the end of the school year, ask others or use Brainly and wait. You can do it <3
