My mother suffer from depression. The depression triggered when we start having financial problems and it gets worst when she was diagnosed with acute pancreatitis (an incurable disease that change your whole life; from what you eat to simple activities that you can’t do anymore). She never smoked and never abuse alcohol so the condition of pancreatitis was gallstones. She had surgery to remove the gall and she expected to be back to normal.
There are things at our apartment that have to be fixed but it is too expensive. After this disease she see herself unable to get a job anymore because she don’t have energy and strength to work, her body simple can’t do any effort.
So one of the main causes of depression for most of the people is losing their independency and being financially stable.
