You're right, life is real and often quite hard, too.
Many people don't mind at all to take (and show) photograph depicting suffering and weakness, as long as they are someone else's.
But it takes real courage to show one's own weakness and suffering.
IMHO I think you did the right thing showing these photographs, because they speak loud.
They speak loud of yourself, of photography in general and of us viewer (or, at least, of me): why it is easer to feel closeness when suffering, instead of happyness, is involved?
