So sorry to hear of your disappointment.
I think you look absolutely lovely.
Models of many different shapes, sizes, and ages are used SOMEWHERE. Not everyone is cut out to be a Vogue-style fashion model.
You can contact any agency, even ones who have rejected you, and ask them what other specialty agencies that might be more suited to you. There are models for catalog work, corporate, advertising, fine art, and, I'm sure, more than I know of.
Don't give up just yet, but educate yourself about places to contact that are more likely to hire you, or at least to guide you.
Good luck to you.
