Mums funeral

Less than one minute read time.
My mum fought for two years she was diagnosed with lung cancer, non smokers lung cancer which spread to the brain and bone. She was my best friend. My sister and I fought every step of the way with her. She died 30th December 2012 and since then I have been in complete denial and on auto pilot. Is that normal? Her funeral is 14 January. My sister is going to see her in the chapel of rest but I don't think i can. My husband is going to go for me and read her a letter from me and leave it in her coffin. She knew every day how I felt about her even before she became poorly. I feel totally alone in life now. My mum was who I turned to in every situation.
