What Do I Do Now?

Around 10:55 pm CST on 8/3/2021 my brother got in a wreck and passed away, now I just don't know what to do with myself. If there's a heaven, hopefully he got to go there and see our dad and his baby girl that passed last year. Then again it brings me to the point where I'm stuck thinking that if there is a god, it's a cruel and terrible one. Too many good people has passed recently weather it be suicide, covid, or other things and I can't do this anymore... I miss my brother..
