I don't know if I have depression or grief. I was very close to my sister and was with her when she took her last breath. She was brave became blind since 9 then living with an auto immune disease since 20 then a full time wheelchair user then getting cancer and being bed. Bound for 1 year. I feel sad she didn't live her life as she should have and she wasn't ready to die even at the end. It all haunts me. It's hard getting out of bed each day. I miss her more than I can express on paper. Any help please.
