Missing my partner, passed away in June

I am going through the loss of my partner. He passed away in june this year. The docters did not refer him until it was too late..they did not diagnose him properly. They even admitted to not doing so. I am so angry and hurt. My son and his dad were best friends. He misses him all the time as do i. We are at a total loss. I dont sleep in bedroom anymore. I looked after him through this and all can say is thank god for the hospice. He went so peacefully aged 48..
