Wearing heels for the first time in public today…

I’m currently wearing heels for the first time in public today and I feel so insecure about it…I’m 5’9 and probably 6’0 with them? I feel like everyone is looking at me lol 😭 I want to change shoes so bad, I feel ridiculous trying to be like other women when I'm not lol. How to be confident? In my height and my height with heels?
