How do you deal with the death of a sibling?

I don't know what made me search this just now, and I'm not sure how much help I can offer. My 22 year old brother ped away a month ago, it was a sudden death with no cause of death to be found. I'm dealing with a lot of similar thoughts and the overwhelming feelings throughout days (I'm in college too so I can relate to the gpa drop). I think your searching for an answer you'll never find - the pain will never go away. You have to accept the "new normal" of your life and understand that life will never be the same, but it will get easier. Me and my siblings (there's 5 of us) find comfort in the memories, like" hey remember that time.." I think it helps because while we won't be at his wedding or holding nieces and nephews of his, we still do have tons of things and time we did get with him. Stay positive, instead of the we never got to's focus on the we got to's. Never forget each and every day you were blessed with his life. Idk if you can relate to this part either but my brother loved life more than anyone I've met, and its kind of my older brother still leading by example even though he's gone, he would hate to know that anyone wasn't enjoying life, and I find it helps to think of this and walk in my big bro's footsteps and love life just as much as he did. I hope some of that helped, and I just want to let you know you will be in my prayers
