Breastfeeding question

Has anyone breastfed their first baby but not their second? I exclusively BF my son for a year and it was so hard on me, I hated doing it. I feel bad saying it but it truly wasn’t for me. I’m pregnant with my second baby and I really just want to formula feed but for some reason I feel guilty. I just don’t feel like I can mentally prepare myself again to breastfeed. I know there’s a formula shortage and I think I feel guilty knowing I could BF but chose not to. I’m just really set on formula but I’m making myself feel bad.
