I'm so sorry Nick. I wish I could make this easier for you.
Your mom raised a great son. I know you hate the idea of raising kids without her around to help, but I KNOW you are going to be a GREAT dad (when the time comes). She's already given you a wonderful example to follow, and though it will be sad to go through something so big without her, she's already given you all the tools you need. You are a patient, compassionate, caring person and that's all it takes to make a great dad. The other stuff will all fall into place, you will see.
