Can I sue a school for suspension based on a lie?

[teyo]

One day I was pulled out of class to meet with an assistant principal. She informs me of a complaint another student made about me, which the student (a female) said I threatend to kill her. I was confused and told the administrator that I did not make any such threat. To challenge me she says-"Well why don't we call her in here and see what she says." Okay the girl comes in, and I speak to her directly asking why she would make something like that up. The girl admits to lying, and continues to state that she just doesn't like me and wants me gone. Fair enough. She is told to return back to class, afterwards the principal says-"I'm giving you a three day suspension so you can take a couple days off to cool down." I was calm, but completely confused to the point where I couldn't respond, couldn't reject the idea. This is one of many instances throughout my highschool career that ultimately led me to give up on school. Now at 26 I still find myself tossing and turning at night unable to swallow the resentment I feel. To find some peace of mind all I can think of doing is taking legal action against the administrator, but I don't have any evidence. What do I do to keep from going crazy, so I can just go to sleep at night. I just want to be okay.

tbh, I'm from the UK and i had a fake Sexual harassment claim put in against me because some girl "didn't like me" and i'm like you to this day i get angry because of it, but do yourself a favor just laugh at it, she's a total fu*king cu*t don't let her ruin your life because she didn't like you, tbh you're going to get people like that everywhere you go no matter how good of a person you are.

i'd just let it go and move on tbh mate

you can try but your suit will lack merit

The proof of your anger issues back then is that you're still hung up on them 8-10 years later. Grow up and get over it.
