I wanted to comment about your situation and how much I empathize with you. I am so sorry about the pain you are in and the added financial difficulties. Believe me, I understand the pain.
You have your children to live for. They will need you for the rest of your lives as a guide and support and loving father. Please do not consider robbing them of you.
I know you feel down and this is a dark time in your life. Remember that this will pass and you will get to the other side.
Hang in there, I think it would also be a good idea to talk to your Doctor. There are a lot of medications that can help you deal with these understandably painful emotions your are experiencing.
I always remember the Churchill speech - never never never never give up.
I agree that distraction is the best rememdy at this point, go to the mall, coffee shop, bookstore, anywhere where there are people to watch. It makes you realize that the world is full of people and there are so many options.
