Past Tense lyrics

[Verse]
You know I don't got an answer for everything you say
I've been on the brink of going insane
Like every f*cking day
Lost up in my head now
Won't you walk away?
Lost up in my head
I just wish that you could stay
I've been on the brink of going away
Rotting inside of myself but I don't feel no pain
I've been inside of my head now, yeah
I'm a motherf*cking letdown, I know, right?
Say you saw me on the freeway last night
[?] for the same sh*t as last time
See me [?] on the interstate
I been gone off of the drugs, they make me feel right
Ridin' round, make me feel like a cool kid
Even though I know that I'm still useless
I been feeling like the past tense
Death+, f*ck the rest, it's nothing, b*tch
