How do i know if i'm emotionally retarded?

Although I do not experience the same emotions that you do around physical contact, I do have insecurities about my "normality". In todays society, it is almost inevitable to feel "weird";everyone goes through this, trust me. I suppose that i am popular enough, but still i feel as though I am much much different than...well, everyone. I have been told that this is natural. Just be who you WANT to be (it is difficult for some people, including me, to be who they "ARE" because we are socially unfit i suppose) If you are true to yourself and the people that you know are trustful, then you will be ok.
