Is supression of feeling harmful? Me?

It's been 3 years, I'm unhappy I had an accident in 2019, from that day my family stopped me from meeting my friends, going out, hanging out socially. & They kept scolding me with derogatory words which went into my sub concious. Whenever I try to sleep, these incidents come in my head because of which I couldn't sleep properly from last 1.5 year. I have life goals but having trouble to achieve them. I have been avoiding this feeling and trying to be happy but everyday it just comes in my mind. They never acknowledge that I (a child) can be sad because of their actions. I literally lost my smile, & I'm more disappointed with the question that "is this my parents want to do with me?" . They always seemed concerned others things rather than my sanity. That's why I hate confrontation, because they won't acknowledge I'm having exams soon & these things are hampering my studies alot! No sleep! Stress! Anxiety! Trauma! & This happened with me when I started perceiving the outer world!
