My brother and I were really close. And suddenly out of the blew he moved 200 miles away and I can't get over it , please help ?

There is not a lot to say here. You will just have to adjust. There may be a reason behind his moving that may or may not have to do with you.

How old are both of you ? Why did he move, as adults we often have to move with jobs, for schools and more. That is a fact of life.

With cell phones that have unlimited minutes, internet video messages, email, text message, there is no reason you can't stay close
