I don't have anything to add, but will echo the sentiment. Like Rick, I don't have any personal experience with what you and your family are going through, but I have a tremendous amount of respect for your situation. I can also assure you that everyone in this group admires your courage and your spirit, and no one looks at you as anything close to a failure. In fact, I'd say the opposite, as you're clearly capable of putting your priorities in order (family first!), and it takes a true dedicated father and family leader to be able to do that.
Best of luck to you and the family, and if there's anything that myself or the group can do to help you out, please let us know!
