I accidentally got kind of annoying and now my friend and her parents are ticked. What to do...?

so I'm only in middle school so plz no "get a job" or "grow up" comments.:) I was asking last minute if she could sleep over cuz I was sooooooo freakin bored, but she said she had swim team in the morning and I had been so excited about being able to camp out that when she said that she didn't want to come I didn't know what to do. I kept asking her to just se if her parents would let her come over but she just wouldn't and kept saying that we wouldn't have enough time. Finally she asked her parents but I'm getting a really strong feeling she told them to say no. I wasn't really thinking and left a message that was honestly pretty annoying but she does that to me all the time and we both just laugh at it, but now she and her parents are super mad at me. What do I do?
