I think, as a parent, be aware that sometimes a traumatic event will happen. And there might be some sort of depressive episode following it. Be prepared and willing to ask for help from friends and family or your partner in case a depressive episode occurs afterward. That's a normal process for most people. And then, ideally, get a therapist immediately. The longer you go without working through the trauma, the more damaging it's going to be. And it may not be accessible without help.
