As to where your d12 would go if something happened to you, this is something that you will need to discuss with a lawyer at some point. Given your h's history of addiction, the lawyer may very advise you that she could live w/someone else as a "guardian" to oversee her education, etc. Again, this is something that will need to be looked into sometime in the future.
I'm sorry to read about your friend. Cancer is not choosy when it comes to knock at one's door. I've seen a lot of people who were healthy and did everything right and still they were diagnosed with cancer. I do hope your friend can beat it and go on to live a healthy life.
Well, at least the editor made mention that he saw some effort. Accept the acknowledgement and continue to focus on what you need to do to hone your skills on getting this paper out each week.

I know, it's a harsh reality, but the bottom line is the final product and the $$$ coming in from interested readers.
Now that you have a better understanding of what he's looking for and what you need to do about Page One, I think you can figure out how to work this situation out and I do know that eventually you will get the hang of things and you won't stress like you are doing these days. You are still learning and yes, it's stressful when you've got someone breathing down your back like your perfectionist, but take his comments and suggestions and use them to your advantage to make a great paper.
Tackle one thing at a time and your list won't be so overwhelming.
BTW, how is D20? Is she behaving herself not taking everything out on you?
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
