Lyric discussion by x7Kuroneko7x 

I thought that a guy is doing something dangerous and regrets doing it because of his love for another girl and realising how much he loves her and he just wants to spend time with her.

--I know that you really wanna go, --Your mind is runnin' outta gas just relax and recap and relapse tonight. --My body's jumpin' and I, go through the motions, --And I'm leaving on this journey, maybe someday I'll come running back to you!

I think this part is describing right before he is about to leave, and that the girl wants to go with him to help/be with him and that she is afraid.

--Her heart, in my hands, it's too bad, no regrets... --I don't wanna see the day, her tears are falling on my grave.

He knows that she loves him and that it will end up in her being hurt if he dies.

--(come running home, come running home!) --This is my one chance to take back, no regrets...

Him telling himself to go home or stop doing what he is doing.

--Let's go! --I just wanna let you know, this situation leaves me outta breath.

Him deciding to leave and telling her that he hates his situation too.

--I only think about her, must get to her, cannot lose her...

Him realising that she's the most important thing to him.

--You know that I will not let this die, life support systems and my mind on rewind and rewind and rewind!

Either he is thinking all of this after he has been hurt bad, dying, or before he gets to that point. He wants to go back and spend his time with her.
