moms of girls? any advice?

I'm having a girl and I'm terrified. I didn't have a very good social experience and went through some traumatic things, and have said I want boys-- only boys-- since I've been in middle school. Compared to me, my brothers had such good experiences and full lives, and I'm so much more comfortable around little boys! Even when it comes to my nieces and nephews I feel so awkward around the girls.
Finding out I was having a girl was like a physical punch-- mostly because I'm so, so scared for her. I don't want her to be like me and I don't know if I have the facilities to meet a girl's needs. ☹️
What have your experiences been with your little girls? Are they really very different? I already love my daughter with a fierceness that surprises me. I just want her to be safe and happy and loved by everyone. It's so much harder for girls.
