I just need advice or someone to tell me what I did wrong...just please..anyone...

I've been getting insults and basically everything thrown at me since I turned 15...Im almost 19 now. I thought it was just because I really did something. But today it really got to me...every single thing... I got everything thrown at me today and the past few days...Im always blamed for something I didn't do. And I can't help but stay quiet. Im afraid to talk, Im afraid to defend myself and Im so tired of it...I really don't know what to do anymore...I feel like Im not counted as a human being. I always feel left out,ignored and I always feel like I don't matter. And sadly this is happenining in the family. Its all towards me...always,all the time...no one else,not my older sister,not anyone of my cousins...just me... I don't know what to do anymore...I try not to cause problems but the more I try to avoid causing the more problem I cause...I just need help...someone help me please...
