Scared to go to school

I have mid-wavy hair. I'm 14m and still haven't found my perfect hairstyle. It reached a point where I actually quite liked it. Eventually, it got too long, and my mum forced me to cut it. The problem is they cut way too much, and it's not too bad, but it definitely doesn't fit me like before, so I'm literally scared to go to school. I'm going tmrw so I hope it'll be good.
