me quieren agitar

They (you all) want to get me worked up (agitated).

me insistan a gritar

They (you all) insist on shouting at me

soy como una roca palabras no me tocan adentro

I am like a rock. Words do no move me (touch me within).

hay un volcan, que pronto va a estallar

There is a volcano that soon is going to explode

quiero estar tranquilo

I want to be calm. (tranquil)

At first, I wanted to translate the first 2 as they (or you all ) want me to get excited or you insist that I shout, but when the infinitive is used it signals that there is no subject change.

quieren que me agite (you all want that I to get worked up)

insistan que yo grite (you insist that I shout)

"me quieren agitar, me insistan a gritar, soy como una roca palabras no me tocan adentro hay un volcan, que pronto va a estallar, quiero estar tranquilo"

Better Translation:

"They/You all want me shake, They/You all insist on yelling at me, I am a rock, Words can't hurt me, Inside there is a volcano, That is going to erupt soon, I just want to be calm.

It should be insistEn here, no subjunctive needed.

It should be insistEn here, no subjunctive needed.

It might also be "incitan a gritar". They urge me to shout. I think it fits the context better
