Scared of being targeted please help me calm down

The man who raped me will be going to jail for 5 years, but he is known in gangs. I'm so scared. I saw on his Facebook his friends were saying "we know the truth and we'll deliver karma" amd stuff saying they will "take care of the one who lies" meaning me (even tho i didn't lie, he even admitted 5 times under oath and in private) and i am so fucking scared for my life and my families life. I have him blocked on everything but i am SO FUCKING SCARED SOMETHING BAD WILL HAPPEN. triggering my PTSD I'm so paranoid. I will never look at his page again i never want to hear his name but he knows where my family lives and I'm so scared someone he knows is going to hurt us. Also when i was giving my testimony his father tried to get up and attack me in the courtroom, he got arrested but clearly they are stupid and will do anything and I am so so so so so scared.
