Little Brother tries to ruin my life

Hey guys, how do you deal with your family trying to bring you down in society.

I believe everyone has their moments that aren’t the brightest and a side they show only to their family.

My little brother recorded me 5 years ago, flipping out and cussing when I couldn’t get my car up the hill on a snowy day. No one would help me push my car up for safety and I overreacted.

Till this day he continues to show people the video to show others I am not as nice as I may seem. He threatens to show the guy I like. He has shown many guys I’ve been with in the past. till this day people who ask to see a side of me that’s “not so nice” too. It’s disgusting.

He also beat me pretty bad 1 years ago and constantly tells me he is so proud that he did.

Telling his friends he hates me and beats me/does not respect me.

My parents don’t care because they don’t think his actions are as serious as I tell them because he is younger than me. He’s a teenager 16 years old.

I just don’t understand why I get so much hate because of the video and for him beating me up.
