I am so sorry for your loss. I too lost my father (several years ago now) and found that it caused so much depression I did not know where to turn. I wish I had this board when that happened.
I don't have any great suggestions for you because time was the only thing that made it better.
If you are not seeing someone for depression and CP, perhaps it would help. You have had a horrible time lately and just finding someone who honestly understands may do a great deal of good.
I hope you will find pain relief soon and that your depression will lift to blue skies and sunshine. I imagine you could use a little sunshine and a little rest.
Peace be with you my friend.
