Getting nervous

So I wanted my little boy so much, I’m due 8th of March and I’m starting to get really really nervous about how I’m going to cope as I know it’s not easy, I’m just worried about if he will like me, if I’ll have a bond with him, if I’ll make a good mum. I’ve been so excited up until a couple of days ago when I turned 21 weeks. I know I’m ready for it, I just don’t want to do anything wrong! I’m not scared of labour or anything, just what he will think of me. I love him so much already and I just want to give him the world. Has anyone else felt like this or know anyone who has and got any advise?
