Hello Milly. I hope you are feeling better at this time.. You may want to see if tutoring is available at your school, or if you can get outside tutoring so your grades will come up. Maybe you should thnk about seeing a counselor if your grades are due to depression. Being a teenager is hard if you are going through depression, there is much help out there for depression, and learning problems. I hope things get better for you soon. Email anytime. sincerely Soidhonia
