Help Me: Mattheo Riddle/Regulus Black soulmate AU

Im rewriting it, and starting the first few chapter before publishing it. I've got zero motivation right now, so I apologize. But I'll do my best :)
Nora is just an average, plain Slytherin. At least she is to everyone around her. But if two slytherins and all their friends take a liking to her, will they be able to break down her walls and the shell she built to protect herself?
⚠️ there are trigger warnings, but I will write a summary of it without the trigger as best as I can. :)
As of now, the triggers are

Abuse, emotional and physical, from her father and death eaters,
implied SA but not full detail,
SH (self harm),
ED (eating disorder)
Depression,
Past Attempted Suicide, (;)
and Social Anxiety
I'm not sure if this counts, but invasive thoughts (unwanted thoughts of aggression, sadness, romance, and other thoughts)
⚠️

This is an OC book, and if you don't know what that means, an oc is the main character that is made by the author. It's easier for me to write like this, and gives an idea of the character. You can just change the description, if you want, to fit you. Please dont take my works. You can use some of these ideas, but please change them up. Thank you! Enjoy the book.
