A failure?

Nena
Will I be considered a failure if I decide to give up on breastfeeding? It's sooo much work to me, and I've been doing it for about 3 weeks now but it's become a hassle .... Doctors keep telling me oh you should continue, like okay, but my milk was being fortified w formula anyways & I'm not always able to pump and breastfeed at certain times .... Idk if I should just let my milk dry up, or continue to go through what seems like eternity constantly having to pump & store & pop out a boob ... Plus I believe formula will fatten him up faster as opposed to just my breast milk ..
