Terrifed to be a ftm

So i have about 10 weeks until my beautiful baby may make their big arrival and i am so excited but absolutely and unbelievablely terrified. We have a great support system and have been given helpful advice and help from the experienced parents in our lives and my partner is so relaxed about this but i am literally scared i am going to mess up. I have neices and nephews and have been around babies and children plenty in my life but ive never had any real experience with a newborn, let alone had to raise one. Ive wanted to be a mum for so long and i am beyong happy but im terrified that im gonna mess up so badly that i end up causing issues or hurt towards my baby solely because i dont know what to do. Everyone says not to stress and that itll all come to me and that i will 'just know' when it comes to my own child or i will pick up their cries and needs but what if i dont? What if this foesnt come naturally to me? What if being a mother doesnt just come to me or i dont get the hang of it. I know its probably just first time jitters lol, i just want to be the best mum i can be for my child.
