Migrating Accounts Is Not Good.:(

When I Was Going To Make An Account On Mojang.com I Did Not Know It Would Make It Where I Have To Use An Email To Log In To Minecraft, A.K.A. Migrate It, So One Day I Was Watching A Video On How To Make A Server, And Then I Made One And Then Clicked On It...And Then It Said "Could Not Verify Username" BECAUSE I USED AN EMAIL!! > So Could You Please Make It Where You Can Un Migrate You'r Account?
