So how do I deal with awkward conversation conversations?

so recently at school, I was caught writing a very interesting book which was confiscated and sent to the school counselor, but there was an entry in there about my world, geography teacher about how I liked her and I didn’t really understand why people talked about her behind her back so much and hoped that things would go well in her life but there was also a lot of entries about poison, which made the school believe that I was a murderer, and they told her because her name was in it and now I’m completely afraid of the awkward conversation ahead and the last time she pulled me out of class just to tell me I had a few assignments missing. I was afraid it was gonna be that conversation about what I wrote in the book about her and so I tried that hack you use when you’re in labor where you squeeze a comb except I was doing it completely wrong because it was with a pen and I was pushing it into my thumb, causing some pretty bad bruising and even at that I didn’t really do much cause extra pain and anxiety about what would happen to my thumb next so I’m just wondering are there any better ways that actually work instead of that? Because I am absolutely DREADING going to school tomorrow
