Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
You should look into seeing a counselor at your school. When I was your age, I was too afraid to speak to a counselor and ask for help, and it is something I deeply regret. It could have saved me years of suffering from my depression. Don't make the same mistake I did. Also, make sure to get regular exercise. Exercise is more effective in treating depression and anxiety than antidepressants.
