Take one second, one minute, one hour at a time until you can figure out what you are feeling and what you need. It's a roller coaster of emotion and grief is not linear.
Deal with it.
My aunt died nearly 3 years ago and my grandad died 2 years ago and it still upsets me to think about them being gone. I wouldn't really say there's any certain way to deal with it, just try and remember the good times you had with them, that helps a little :)
its not easy to handle, you try to do the best you can
No human that has been close to me has died yet. There have been some relatives, friends not in my closer circle, and I was sad, but not overly. Now, my favorite cat died and I came unraveled. I was a total mess for months.
feel a little sad, and wished they didn't leave this world. usually feel that way for a few days then move on.
I secretly meet their friends and go visit their graves. Do the thing they like to do and remember them in my prayers forever.
