Hi - I really, really like what you've done here. I agree that this sounds like something done slowly in a minor chord progression. The only lines that I don't really care for (and bear in mind, this is just my opinion so take that for what its worth) is

"You used to hold me in your arms

Now our love is in alarm"

I'm not sure what would work better but this just seems a little 'jarring' in context of the rest of the lyrics. Other than that, it flows very well. Excellent job. Keep writing! :D
