What next?

That's a thought that comes to mind since losing Jack. I'm scared of what else could happen. While I was pregnant with Sam, I thought the next bad thing to happen would be losing her too. I also am scared of losing other loved ones. When Sean isn't around, I'm scared he will be taken from me. I can't sleep well without him by my side. Now that Sam is here, I wake up at night making sure she is still alive and I wake up every morning grateful that she is still breathing. We lost our son. What is the next bad thing to happen to us?
