Are my looks putting off potential enployers?

I have been unemployed for 2 years and have not had a single interview despite handing a string of cv's in to about 40 different buissnesses numerous times i have come upon the conclusion that when handing in my cv my 4 foot 9 stature and the fact that without make up i look 13 is putting them off i am especially convinced of this when i think back to my last job where i had asked to be trained in the bar i can count on one hand the amount times i served for maybe 20 minutes and at the same time two girls who worked promotions for about 2 months got the training and i can easily say that they were more conventionally pretty than meybe 20 minutes and at the same time two girls who worked promotions for about 2 months got the training and i can easily say that they were more conventionally pretty than me
