The feelings you are experiencing are part of a normal grieving process for a large part of your life that has gone. So many things you used to do were as part of a couple, and you have to take time to adjust to your new situation. While that time passes, be comforted that, once you have learned to live as a single person, you will never feel this trepidation again - it's like riding a bike, once you;ve learned to do this, you will always be able to do it again after any future relationships break up. The feeling that no-one will ever fancy you again is perfectly natrual, and totally unfounded as well! When you are ready for a relationship, someone will come along. Take it from a man, a girl who appears uninterested, as you will for a while, is deeply attractive, you will have no shortage of interest, but do heed the previous advice, and take your time. Enjoy the single life until you are ready to love again, and that is definitely 'when', not 'if'!
