Who am i

Yo I could strike physically or mentally or
I exist in you, I'm wit' you get your sense of the call
I have no sense of humor, I vent, you must
Stay the fuck out of my way, I'm too much
I'm the first to let you know if something is real, I come
Right before the comforter squeal, I'm something you feel
Go ahead try to fight with me nigga do the best that you do
I could be hard, I could be soft I'll even let you choose
I exist upon the impact of a flying fist
Always show up unannounced on you nigga, I'm kinda sick
What that nigga shoot that gun at me for, you still alive
I'm a riot not numb anymore nigga now die
I command fear, so be afraid, be very afraid
You get carried away, then I'm a see you
Nigga you better keep the heater with you
I'm waiting for you dog
Cause theres somebody that wanna see me with you
Keep an attitude, I'm evil
Spiteful, stay mad at you motherfuckin' practical people
Trust the one you love and I'm a make you cry
You even try to fight drugs and I'm a take its side
The only thing that stronger than me is time, and yours is limited
And I'm involved in it 'til you all finished
I despise you, thats why I surprise you
Even if your mother dies I'm a fuckin' remind you
I want you walking in front of a truck or a car
Cause I hangs out at these hospitals like a club or a bar
If you afraid be, cause I'm so hard
Only one who can stop me is your God that made me
So, he is your witness, I am your sickness
I got every human being alive on my hitlist
I'm still in your way, I'm still under your skin
You don't want me but you would give me away? Then fuck you
Niggas better know than I'm something they'll never know
All you'll ever
