Breastfeeding and formula

Melissa
I had a crazy long induction and labor, and due to some complications with my body I don't produce a lot of breast milk.  I've been to a lactation consultant twice and we determined that I should stop pumping and just breastfeed and supplement with formula.   I know she doesn't get much from my boobs, and part of me wonders how long I should keep both up and eventually just do formula only?  I feel defeated and guilty every time I breastfeed her knowing I don't have a lot to give ;(.   Anyone have a similar situation that can offer advice?  TIA
