Snap out it' is abusive. It kicks people when they are down. It makes people in pain feel more hopeless, more powerless, more frustrated, more estranged from humanity. It says, 'I don't want to be bothered with your pain any longer.' For people not in great pain, "Snap out of it" may be helpful advice if they have trouble getting going in the morning. For the despairing, however, it has no positive and many negative consequences. None of the conditions associated with suicide can be snapped out of.
