Quote from fortunatti:
Nothing bothers me more than the "i dont understand depressed people blah blah blah they're stupid for killing themselves why weren't they tougher, their problems are smaller than other peoples etc etc."
Suicide is the final symptom of depression - which often has nothing to do with the size and scope of an individual's problems. Its a physical/chemical imbalance in the brain triggered by something (genetic or otherwise) that causes feelings of hopelessness and and decreased ability to cope. It's a medical problem and it can usually be be treated with some combination of therapy and or medications.
People often perceive this as weakness or charcter flaw. Depression is not something these people choose, its a disease and clearly not their option. Yes, in a way this dude failed himself, but to a much greater extent he was let down by a failure of the people around him to notice the symptoms and get him help.
