stressful life events – these can be unwelcome or traumatic, such as being bullied at work, getting divorced, or being attacked/abused

lack of interest or reduction of pleasurable activities – Sometimes, due to circumstances, you may reduce activities that you gained pleasure, satisfaction, or achievement from. You then do not increase these activities as soon as possible, instead you may forget just how much you benefited from these activities, causing you to have a lack of interest in doing them.
loss – this can be the actual loss of someone through death or disappearance, but it can also be a major life change where there has been an adjustment and a loss of role or identity e.g. redundancy or retirement

physical health – various illnesses can contribute to low mood such as hormonal problems, menopause, and diabetes
