It's not all or nothing and you (and your baby) don't need to get it immediately.
Different things work for different people but the worst piece of advice I was given was to just persevere, eventually baby will get it and FF will affect your supply if you let so much as a drop pass your precious baby's lips. Truly awful advice in my case and my baby almost ended up back in hospital due to excessive weight loss. I had a very hungry, unhappy baby for the first few weeks. By comparison, your baby is getting enough milk and you are doing exactly the right thing.
If you want to FF, your baby will be absolutely fine and no issues. You are not letting them down in the slightest.
If you want to persevere with BF, also fine. Many babies start off mixed fed for a variety of reasons and then as their mother's supply increases and they become better at feeding, eventually go on to be almost exclusively bf. This is what happened with my baby. After a truly awful start and lots of pressure put on me by various people not to give formula (which in the end I ignored and slipped baby a few bottles of formula to stop the hunger screaming), both my baby and I eventually got the hang of breast-feeding and I ended up breastfeeding until 18 months.
What I would say is that if you choose to continue, breastfeeding can be a lot easier than formula feeding in terms of not having to sterilise bottles/prepare feeds etc. I was glad in the end not to have that hassle. On the other hand, your partner/other people can help a lot more if you're giving bottles.
Currently pregnant again and this time I will ignore everyone else's opinions and do exactly what feels right for me and the baby, which will probably involve a combination of breastfeeding, expressing and formula to start with.
