Take your time to recover. It cuts deep but with time you will move on. He will stay in your heart and memories. Try to figure out how to deal with it best. Some like to be close to family and deal with it together, and some distance themselves to overcome the pain. I hope you and your family will feel better soon.
But man take your time. I know family stuff is hard. My cousin died last year at the age of 31 and my family still aint fully over it...please dont rush things bro <3
