I went something very similar and can totally relate - - Lost job on birthday - off work 8 months; Mom dies of Cancer - 4 weeks later; Wife of 7 years has affair, ends in bitter divorce that takes two years to resolve; Lose House, Car and have to liquidate all assests in process; go from being with my kids everyday, to seeing them every other week and finally when I think it is over - dog of twelve years dies in my arms.
