New pop radio song, lyrics are like "I'm so lonely", who sings it and what is the title?

I'm not thinking of Akon, it's a different guy. I've been hearing it on the radio for a couple of weeks now, it's so good, I want to know who sings it!! It's a male singer.

I just heard the song again. More lyrics are "I'm so lonely.... I'm so lonely... when ya leave me..."

Is it one of these?
