Today while I was at work, the chorus to a song just popped into my head. It's ages since I last heard it, so I can only remember the lyrics from the chorus:

This is how it feels to be lonely
This is how it feels to be small
This is how it feels when the world means nothing at all.

I've tried internet searches with no luck, and I might not even be getting the lyrics 100% correct. Part of me thinks its by The Smiths and the other part thinks thats completely wrong.

If anyone can tell me what the song is called and who it's by I'd be very grateful.
