Tell me what’s wrong with my brain 'cause I seem to have lost it..

Who could tell the story better
About the things that I went through
...
I'm waking up in night terrors
I feel the weight of the world crushing down on me
I can't calm down, I can't think straight.
...
This room feels like its going to explode.
You have to fight to stay in control of the situation.
Anxiety, Anxiety you give me no mercy.
...
I'm sick of feeling like I'm losing my mind.
I'm sick to death of being constantly fucking sick of.
I don't know who I can trust.
