Firstly may I say that is very sad to lose somebody so close,I think what you are going through is perfectly normal,your life will never be the same,how can it, but it will get better,as for thinking somebody is still with you is how it is,the realisation takes a long time to register, after my mum died even after a year or so, I would sometimes think ,oh mum would like that, then it would hit me again that she is not here,I think we wish it was how it used to be,but it never will be,these feelings will pass,and sometimes you might feel guilty at laughing at something,but again the distance between these guilt feelings gets longer,but it will take time, so don't worry you are perfectly normal, all I can say is even after a year or more if you want to cry,then cry,just don't bottle it up,good luck, Ray
