I'm scared

I'm scared when I have a baby I won't be the mother I need to be... like I won't do anything right .... like I won't be able to take care of my baby like a woman should. The reason I feel this way is because I don't have any experience with children ... I've never held a baby.. never really baby sat any kids..never changed a diaper..no type of interaction with a baby what so ever..and I'm the baby of my family (23 y.o) so it scares the hell out of me... will I hold my baby right ? .. will I be able to breastfeed?...my SO has younger siblings ...he is 26 and has a 8 y.o little sis that he took care of he has that experience that I don't have and I just feel like if I'm doing something wrong he'll look at me like I'm crazy.... does/has anyone else feel ot felt this way before??....
