I'm on my way to heaven (Wherever you are, now)
He is trying to make his way out of drugs and no matter where you are, he wants you to stop, NOW.
In the song he is referring to an overdose. The song Mr Rager is about his cocaine addiction. He is saying he is dying, “I’m on my way to heaven.”
He could also be saying that he is on the way to beating his addiction. Heaven is the release he will feel once he’s no longer addicted drugs.
