In the chorus I believe that Eminem is coming back full force out of a deep depression and a dark time in his life. He is saying that he's coming back without worries of regression. He's also saying that if anyone else has the problems he had he knows what they are going through and he will lift them up. Eminem is saying that no matter how hard life gets you will have people to lift you up along the way and people have been down the road before you and you are able to come back from it because others were able to.
