oh, recf, i can SO identify with how you are feeling right now, and i am sorry you are hurting. please remember that we all have moments of insecurity, but they are simply that...moments. even the strongest of people will have occasional doubts.
you ARE sexy, cool, and, more importantly, worthy of being told so by someone special EVERY SINGLE DAY.
keep your head held high and take care of yourself. let things happen in their own time (hard to do, i know) and you WILL be rewarded for your patience.
