Chord/Tab song: Circuits and Wires

This isn't great.
The "don't speak" part is almost certainly not right.
However, since there are no other chords or tabs, I figured maybe someone might find mine useful and
maybe make suggestions as to how to fix it.
Hopefully it helps some!

Capo 1

[G]I am all circuits and wires
[C]Conducting symphonies of [Em]heat exchange and [G] energies
[G]Fueled by a nervous system [C]thrust through the great unknown
[G]A timid mess of [Em]frightened bones

[G]I pledge to make no difference
[C]I aim to take no stand
[G]This bitter silence is the [Em]only play I have

[G]In light of all their laughter,
[C]I'll take to keeping shy
[G]A resolution that I've [Em]finally had enough

[G]Can't speak, can't speak, can't speak at [Em]all
[C]Don't even think you know the [G]reason

[G]I know there's [Em]something wrong within my [C] faulty[G] brain
I lack the [C]proper be- [G]havior
[G]My temper [Em]addled tongue can't seem to [C] force it [G] out
The [Em]words that linger [G]inside [C] me

[G]Can't speak, can't speak, can't speak at [Em]all
[C]Don't even think you know the [G]reason
[G]Can't speak, can't speak, can't speak at [Em]all
[C]Don't even try to [G]understand

[G]I am all motors and gadgets
[C]Organically designed [G]to last a finite [Em] length of time
[G]Locked in this rotary motion, [C]the wheel spins round and round
[G]I comprehend it all but still can't make a [C]sound

[G]I know there's [Em]something wrong within my [C] faulty[G] brain
I lack the [C]proper behavior[G]
[G]My temper [Em]addled tongue can't seem to [C] force it [G] out
The [Em]words that linger [G]inside [C] me

[G]Can't speak, can't speak, can't speak at [Em]all
[C]Don't even think you know the [G]reason
[G]Can't speak, can't speak, can't speak at [Em]all
[C]Don't even try to [G]understand

[G]I am all circuits and wires
[C]Conducting symphonies of [Em]heat exchange and [G] energies

[G]My temper [Em]addled tongue can't seem to [C] force it [G] out
The [Em]words that linger [G]inside [C] me
