Hello and welcome.  This all happened so quickly I can understand that your emotions are all over the place.  It is a sad symptom of the problems facing today's younger people that they are all still living at home but at least it means that you have the opportunities to talk to each other regularly and support each other.   Just talk about how you are feeling.  I am attaching some information about grief which you might find helpful - this varies so much from person to person and each person just has to do whatever feels right for them.  When first my mam and then my dad died I would keep things that had a connection with them, looked at photos (I still have their WW2 wedding photo - clothes rationing still in force) and thought about them. Supporting each other and ultimately time are the things that will gradually help so don't expect too much so early in your grief.  Annie
