I'm so sorry for your loss it's truly Heart wrenching My mum very quickly deteriorated aswell, we all thought she had longer but suddenly went down over a couple of days it was like she had accepted to give up and just let go. Within 18 hours of the injection she was gone. I also watched my mum take her last breath and that moment will never leave you, find strength in the fact she is no longer suffering although this is very hard to accept. Life will never be the same but we have to live on and find some sort of happiness without them, even though a huge hole is left In our lives they would not want us to bury ourselves in grief forever.
