Your guilt is misplaced. It wasn't your place to take care of them, to begin with. You did what you could, if there isn't any more money, then that's it. Guilt is only useful if it motivates action. Feeling guilty is not going to change the fact that you do not have any more to give. I can tell you if my son were in prison, I wouldn't give him money. I can see helping out the wife and grandkids, however, after fifteen years, some of those kids should be grown and gone.
