Hi Cat,
welcome to the forum, hope you stay and enjoy our community.
I like most of your lyrics and have a couple of suggestions. I don't hear a traditional chorus when I play your words through in my head. Although I do hear a repeating section which may be a refrain or a tag.
I'd remove the first part of the chorus from "If the liquor" to "no more". It doesn't really add anything to what has come before.
I like the devil and the reaper lines but I'm not keen on the letting them in lines. The God help me lines work but you may like to consider postponing their introduction until the second devil and reaper chorus, refrain, tag. It allows the song to build up first and will be a surprise to the listener.
I'd start the second verse (?) with the lines about the drugs followed by looking in the mirror and the thoughts of suicide. Then into the final devil and reaper and the outro with God help me.
Feel free to ignore me if you disagree.
Hope you stick around and post some more lyrics and comments on other people's work as well.
Keith
