personal question

so I've been debating as the time gets closer to having our baby. I didn't breastfeed with my daughter because I didn't really understand and she didn't really latch on. Now I'm debating on doing it with my son when he's born, but I don't know if I really want to. I know it's great for their immune system etc but I remember the pain. Is there anyway to make it less painful? Does it make me a bad mom if I don't breastfeed?
