I second what's already been said; sounds like your friend is operating a little out of fear as she is now taking a look at the part alcohol & prescription meds are playing in her life, even if she isn't verbalising it. As for the constant questioning, sounds like she's genuinely concerned for you, it's just that it's a bit stumbly and she might not know how to convey it otherwise. Try to stay patient!
Kudos to you for doing something about it now; I relate to that anxiety before picking up, for me it (was) a total physiological transformation (mouth watering, stomach-turning, antennae-pointing kinda stuff, ew
). Hope you keep posting here & continue to get professional help. This is for you; the bottom line is that it doesn't have to be on anyone else's terms, minimised or justified away. Best wishes
