I'm not sure :(

You're a part of my life that I can't live without, 'cause you just like drugs for me.
Every single day I need my drugs to keep me breathing,
just like I need you to keep me still alive.
Even I know that someday I should stop to use drugs, stop being a drugs user,
it means stop being around you and move away
But I'm not sure,
I'm not sure I can do it, I can live without you
I'm not sure I can handle it when the time comes
