Im very sorry for your loss man. I know what its like a few weeks before you posted this my father at age 48 died I was 14 at the time.But understand, you still have a relationship with your brother, its just a differnt kind of it now. every time you pray for him or think of him, you are communicating with him. Also, you have a gift of helping others grief now. you can say i understand your pain, you can help them guide to cope with these feelings in a right away. that is a gift no one can ever take away from you. also enjoy life dont isolate yourself, you lose relationships with other people you love.
