Anyone stop breastfeeding after 2 months?

I have an adequate supply, my baby has a great latch, & she’s gaining weight perfectly fine. But I just want freedom. I’m so tired of being the only one who can feed my baby, even if she takes a bottle I have to pump in order to supply that bottle & pump when she eats so I don’t get engorged & my supply doesn’t drop. I’m just overwhelmed supplying my baby’s only source of nutrition. I want to stop breastfeeding but I feel like I’m being selfish & I just want encouragement to continue or someone to tell me it’s okay.
