Bottle feed or breast feed?

Question

I am expecting my first baby and I am so torn about nursing or not. I thought I wanted to but have my reservations about it. My husband would prefer we use formula and I'm really shy about nursing. I really want the most convenient method, I'm just not sure what will be easier for me. I also am taking into consideration the cost of formula...breastfeeding would be cheaper...right? Any advice on which one I should choose?
