So sorry to hear you're having these financial worries on top of everything else. It's a shame how this world can be at times. It's so difficult to lose a loved one and yet even during a time like that you still have worldly money problems to cope with as well.
I agree that this edit should really be placed on the back burner for now. Work on it off and on to help take you away from all the turmoil if you need to. But don't let this project be a source of any more stress in your life. If it helps you cope with things, then it's not such a problem, but if it is causing you any grief, put it aside.
