The Only One Lyrics

I thought a similar thing 'Death is hereditary' ...

"When they all come crashing down- midflight you know you're not the only one when they're so alone they find a back door out of life you know you're not the only one

We're all grieving lost and bleeding"

Its like she's just heard of someone else committing suicide (finding a back door out of life) and she realises she's not the only one that feels that way, everyone feels depressed every now and then (we're all grieving and bleeding) the rest of the song goes in a slightly different tangent but still on the same basic lines

I must say that I agree with your interpretation. It's really good.
