You are not a freak, you are totally normal, it just so happens at this time in your life you are not attracted to anyone.
What is probably happening is that you want the attraction to happen so much that you are stopping yourself, forget about wanting it to hapen, just let it happen naturally, at some point you will find someone that you are attracted to might not be tomorrow or even next year, it will happen.
As for being alone, as long as you have your family and frineds you will never be alone.
