I think that the lyrics of From the Inside go well with Star Wars III: Revenge of the Sith. Here's my explanation. Note that i don't use all of the lyrics.
xd "I don't know who to trust"
This goes for Anakin. He can't trust the Jedi, whom he's believed in for so long, and isn't exactly sure at first if he can trust Palpatine.
"Everyone feels so far away from me"
Obi-Wan. All of his friends are gone, and they are far away from him, they are not there anymore, even though they are now part of the force. And, Anakin, is no longer his brother or friend. He is a Sith, his enemy.
"Heavy thoughts sift through dust...and the lies"
Anakin believes that the Jedi were lying about everything, and that there is something bigger going on, something evil.
"Trying not to break but I'm so tired of this to seek every time i try to make myself get back up on my feet all i ever think about is this all the tiring time between and how trying to put my trust in you just takes so much out of me"
Obi Wan is trying to stay strong but all he can think about is the betrayal, the death of his friends, the fact that Anakin has turned, and how Anakin has been left for dead (of course, he doesn't know he's alive). And last, it was so hard for him to trust and believe in Anakin after he turned.
Chorus: "(skip the first sentence)...Cause i swear for the last time i won't trust myself with you."
Anakin feels as if He has trusted Obi-Wan too much, and trusts himself to be safe with Obi-Wan, but no believes that the Jedi are traitors.
"Tension is building inside, steadily"
Anakin is getting angrier and more upset as time goes on.
"Everyone feels so far away from me"
Same as before.
"Heavy thoughts forcing their way out of me"
Anakin's evil spreads throughout him, and is showing itself as the movie goes on.
"Trying not to break but I'm so tired of this to seek every time i try to make myself get back up on my feet all i ever think about is this all the tiring time between and how trying to put my trust in you just takes so much out of me"
Same as before.
Chorus: "(skip the first sentence)...Cause i swear for the last time i won't trust myself with you."
Same as before.
"I won't waste myself on You!"
Anakin believes Obi-Wan is another Jedi scum, an enemy, who needn't be wasted on.
Chorus: "(skip the first sentence)...Cause i swear for the last time i won't trust myself with you."
Same as before.
