Everyone feels sad or down from time to time, but this does not necessarily mean you are depressed.
Depression is an intense feeling of sadness that lasts for a long time, sometimes weeks, months or years. If you are depressed, it can start to interfere with your day-to-day life, wellbeing and physical health.
Signs of depression to look out for
Other signs to look out for are not wanting to do activities you usually enjoy or avoiding seeing your friends. You may notice a change in your appetite and have trouble sleeping. Poor concentration, difficulty making decisions, and being overly self-critical may be other symptoms.
Sometimes you may know what has made you depressed but other times there may be no apparent cause. Remember that depression can be treated. If your mood has been low for over two weeks, you can seek help.
