The symptoms of depression can vary from person to person and symptoms can manifest in the way you feel emotionally, the way you think, how you behave and how you feel physically. Signs of depression can range from feeling low and hopeless, to changes in appetite or sleeping pattern. Depression and anxiety are often linked and many people with depression will also have symptoms of anxiety.
Depression symptoms can range from mild to severe. Mild depression will have some impact on your life, and leave you feeling low. Severe depression will make it very difficult to get through the day and may even lead to feeling suicidal.
Depression can change the way you behave which can then have a negative impact on your emotional and physical symptoms. You might stop doing the activities that you once enjoyed, or withdraw from friends and family. This then increases the feeling of isolation and hopelessness.
