34ish weeks & very unsure about breastfeeding - advice?

Of course I’ve been asked by everyone & their mother if I plan to breastfeed, and I honestly feel so unsure about it either way. I’m so tired right now of feeling like my body has been on loan for 8 months, and the idea of still being entirely responsible for feedings for years is making me so anxious. I’m not saying no to breast MILK (I ordered a pump), but my mind is saying do a mix of breast milk and formula.

I wanted opinions of people who maybe felt the same way, and what decision you ultimately made, if you feel like that was the right decision, etc.

Thank you!
