I am so sorry to hear of your tragic loss!
There are many stages of grief and anger is most definately one of them. I was angry for a long time to when Phoebe passed away.
The people here on yt help me get through it. There are alot of people here that do understand what you are going through and will help you through it.
You are in my prayers.
If tears were stairs and memories a path I would climb up to heaven and bring you home again.
