I would agree with ljoy that
www.hoagiesgifted.org offers some great references. I would also suggest reading some books about gifted adults. Most had similar experiences of feeling different, remaining outside the norm in terms of social experiences, and feeling misunderstood. I also agree that blogs about gifted individuals can be a helpful means of gaining support, as ConnectingDots indicated. See
http://giftedchallenges.blogspot.com/2013/08/top-blogs-about-gifted-children-gifted.html for a list of great blogs.
I hope that you start to feel more comfortable with who you are and find a group of like-minded peers who understand and appreciate you. Good luck.
