How do I get her? She makes me lose my senses....?

My body heats up, A tingle moves across it. I break a sweat and lose the feeling in my muscles and coordination. Shes amazingly beautiful and I feel like she is the one for me. But i am extremely nervous and without words when i see her. I work as a cashier at a independant buffet. Shes one of the customers. She works in the office building that my cafeteria provides service to in downtown Chicago. So when she comes to my register, we have a lil small talk, but its mostly me saying something stupid and akward like if she pllays the lotto. What kind of stupid **** is that? She used to come only to my register but i feel that since ive been fumbling around her, she hasnt came by me. One time we connected eyes for about 5 sec without looking away. 5 sec is actually a long time. Shes everything I want as far as her swagger. She carries herself well, Shes got a mad sense of style. Ive been through a long rltnshp before so i know how to deal with the ups and downs of one. I know id be perfect for her but the only thing that holds me back is my current life situation. Im in a transition in which i moved back home while i continue school. reason being because i was unemployed before this job. So now im in a bind of debt and starting my life over. I didnt want to find a relationship after the one i had but shes making a strong case to change that. I guess my question is how do I approach this Woman of my life. I love my pesonality but i feel like it doesnt match my face. I have low selfesteem and feel unattractive but i do have the ambition to approach her and am not a shy person, though the ironic part is she makes those qualities in me become hanicapped. Ladies Please help me!! Im not a dog.. im a geniune, sweet, funny, and caring person... i think of others before myself. She deserves someone like me but how do i let her know that?
