feeling bad

My baby is 6 weeks old and since birth I've been bf and formula. Now I barely give him my boobs probably once a day or sometimes not even at all. I don't want to anymore but at the same time I do because it makes me feel bad. I don't know why I'm feeling like this towards that. My baby is eating good but it makes me feel some type of way if I just stop completely breastfeeding him. Did you ever feel like this?
