Sorry to hear of your diagnosis Mix, you will be in my prayers.
You saying the above really concerns me. Please, Please, Please whatever you do, don't go back to that shit. You need to be as healthy as possible when trying to fight your fight against this sickness. I know that's easy for me to say, but just remember that all of us here are hoping that you get through this battle. Keep your head up brother. Gods got you.and no matter what don't go back to using drugs.
