Can you find out who hacked you on Instagram?

I hacked my friend's Insta and changed her bio, profile, and posted a couple pictures. Later that day, I was going to delete everything and change it back to normal, but I noticed her password was changed and they had found out somebody hacked her account. They are trying to find put who did it and getting really serious about it. Her mom works for Apple. Can they find out? I am terrified. I don't want them or their moms to hate me. It was just supposed to be a joke. I am really scared. It was a bad thing to do.
