Idk if I’ll be a good mom

Ok so i don’t have that loving nurturing emotional side to me maybe that’s because how i was brought up . My mom isn’t that affectionate n i must’ve got it from her .. anyway idk how i would be as a mother i think i would fail & make many mistakes from the way i think sometimes I’m scared kinda to even have a child i always said i don’t want kids but then i changed my mind n i been with my bf for 8+ years and he really wants a child but we don’t even have things together at all. I’m so lost can y’all give me advice ?
