Breastfeeding troubles

Baby boy is two days old and latched a couple great times but he doesn't every feeding...nurse told me to wait longer and maybe he's a cluster feeder. Waited almost 5/6 hours and sucked a couple times but won't actually latch for a while. Tried multiple positions, nipple shield, everything basically It breaks my heart when we try to get him to latch and he screams....at this point I am completely exhausted and overwhelmed I don't even wanna try breastfeeding but I know I'd regret it. I just want what's best for my sweet boy
