At a loss and so bewildered. Is there any hope?

A good while after my divorce, I gave dating a try. I fell in love again but then after months got rejected. I feel like who I am isnt good enough. Im near 40. Im not some knock out chick and I dont have these amazing outgoing, dazzling, bubbly features about me, im just...me. I admit im kind of quiet, im hard working, but really supportive and caring of who im with. Why isnt that good enough? Why should I have to try and alter my personality to try and find love again. Why cant being me, be good enough for love?
