Chord/Tab song: Heart Attack

Em-G-D-C the whole song

[Em]We share, somethin' so charming[G], still so rare,
and I'm in [D]awe, never been here befo[C]re,
( Tab from: http://www.guitartabs.cc/tabs/t/trey_songz/heart_attack_crd.html )
Repeat Em-G-D-C throughout whole song
[Em]so high, we're still climbing[G],
even here inside these [D]walls,
breaking each others [C]hearts,
and we don't care 'cause we're so,
into deep can't think about givin' it up,
but i never knew love, would feel like a heart attack,
it's killing me, swear i never cried so much,
'cause i never knew love, would hurt this fucking bad,
worst pain that i ever had,
never knew love, would hurt this fucking bad,
worst pain that i ever had,
All the times when i know i should be smilin',
seem to be the time, that i frowned the most,
can't believe that we're still survin',
'cause I'm slowly breakin' down,
even when i hold you close,
And if i lose you,
I'm afraid i would lose who,
who i gave my love to,
that's the reason i stay around,
