Depression is very common but serious mood disorder.
symptoms must be present for at least two weeks.
Treatment: with medications, psychotherapy, or a combination of the two. If these treatments do not reduce symptoms, electroconvulsive therapy (ECT)
Personal experience: Depression is real!! I suffer everyday from it! Most of the time I feel sad or down. Lack interest in some activities especially school work. It has affected my relationships with people. I do go see a counselor at school it is very helpful.
Do not be afraid to ask for help!! It is a very dark path to go down! You are not alone!
