Advice, Help, Support?!

Hi, So, briefly, about a year and a half ago I contacted my adoption agency to inquire as to whether or not they had any other information on file about my adoption (beyond what had been given to my adoptive parents). They did and when they sent me that information I found out that one of my biological brothers was also adopted (both of us were international adoptions). I was curious to see whether or not I could track him down and I have. I'm not quite sure what I want to do at this point and I'm just really confused. My family and friends (who know) are very supportive but it's like they just don't get the feelings. Can anyone else speak to this situation? Thanks.
