Is There Anyway I Can Stopped Getting Shipped Abroad At 14/15 Legally?

Location: Massachusetts

I’m 14 currently and living with my 3 adult older siblings. My parents went back to their country( Uganda) around 2 years ago and are mostly likely going to reside there for their remaining life . My mom might send me there for the summer (my dad has trying to influence her to get me to go and by saying stuff like I’ve not been taken care of ). I don’t want to go because my dad is really physically abusive and strict and theirs a probability that mainly he might try to trap me for the rest of high school and my adult life. They want to take me there this summer but it’s not set in stone. If push comes to shove I want weight my options of what I can do like running away, going to a shelter, or calling cps. Is there anything I can legally do as 14? Will getting my school involved help or the cops? I’ve thought about inflicting self harm or sending my self to a mental hospital if they tell me they are to scare my mom away from doing it but will that backfire with cps? Will hiding my documents will that work? Any advice at all will help

(Also by summer I will be 15 if that helps at all)

EDIT : I didn’t make some things clear so I’m gonna put that along with stuff I missed here

1.) All my family members like me,my siblings and, parents are US citizens 2.) my mom sends money for bills and utilities to my eldest sibling to pay for our house (idk if this is info is needed but I’ll put it in) 3.) all of my siblings are in college 2/3 both are graduating this may and are mostly going to mainly take over the house financials after that because one of them are going to have a pretty substantial increase in income (which is like that may or June)
