I’m suffering, I miss my dad so much

Hi Guys 

      So it's been 8 months since my dad died. I've carried on almost as though it has happened to someone else. But at night when I'm in bed, I feel so so alone and I hurt so much. I miss him dreadfully. Christmas isn't helping. I just can't bear it. I feel on the edge of crying in work. Can't say I've cried yet actually. I held the family together when dad was sick, dying and the day he died and since. But inside my pain is so bad just wanted to be able to tell someone xx
