Don’t want to breastfeed again

So I am pregnant with baby number two! It wasn’t planned but me and my husband are super excited anyway. But when i think about having a newborn again, i get this feeling or pure depression and anxiety. I had a horrible postpartum with my first and I believe it’s because of the stress and pressure to breastfeed. I breastfed him for 16 months, and it was the hardest thing ive ever done. I was put in hospital at 2 weeks PP due to exhaustion and not being able to eat. It was so hard. But I feel guilty if I say I don’t want to breastfeed this child for my mental health. The mom guilt is already here and I haven’t even had the baby yet 😂😂😂😭😭
