1. Feelings of helplessness and self-loathing
This is the most obvious symptom of depression. They feel hopeless and life seems bleak- it looks like things will never get better. Depression also wreaks havoc on the self-esteem of the sufferer. They feel useless and worthless and believe they are a burden to their friends and family. They have strong feelings of guilt and harshly criticize themselves for perceived faults and mistakes. These feeling of worthlessness and guilt can increase and even culminate to self-harm.
Once you know the symptoms of depression, you should act immediately and ask for help. Even if things look dark, you should know that you are not alone and that things will get better. Depression is a curable disease and once treated, patients can return to living a normal, happy and productive life.
