I'm Suffocating...

I am so scared and have no clue why. I feel like someone is coming to get me. I feel like I'm being suffocated. I need out. I'm in a little box and it's locked from the outside, I am trapped inside. Someone set me free. I feel like I'm losing my mind. I can't control it. I'm shaking. I want to hurt myself so the pain will distract from the anxiety. I can't do that. I've come this far and I can't fail now. Not now. I want to sit in the corner and cry. Someone save me from this living hell I put myself in. I can't escape...I need out. I just want to break my bones...one quick snap, it'll be over... But I can't do that.I've come so far.I can't fail. NOT NOW. NOT now... not now.
