oh my dear=i am so sorry for your loss,it IS absolutely normal!!!and DONT let anyone tell you how to grieve or how long. you DO NOT just get over it and move on,you need to grieve and cry and be mad,all those things. It has been 2 years this july since i lost my wonderful daddy and i am still not over it. I often take a walk with my little boxer by myself and think and ponder and cry if i want to. my best place for letting go ,is in the shower at night, turn it on full blast,sit down and bawl all i want to.
please know you are not alone and certainly not abnormal,i miss my daddy every single day,there will always be a huge hole in your heart from your loss,that will never be filled again, yes you can go on ,and you will find the strength and faith to do so,but never think you will "get over it"
