I haven't felt anything in 3 years

My parents have emotionally abused/neglected me for my entire life pretty much and two of my friends have attempted to sa me (not r@pe). I am only here for my little sibling. I feel nothing. I'm just floating in a body that isn't me. I look in the mirror and I see a random person, I don't even know who I am at this point. I'm just numb. And I'm only a teenager.
