I can break you,
Or take you,
And captivate you forever.
I strike you,
In moments where you’re weak.
I strike you so that
Forget me you will never.
This arrow pierces you deep and sound.
Come get me before your life runs aground.
What am I?
I think it may be ...
love
... because ...
Love can break you (or your heart) of course,
it can take you (which has many different meanings here ...),
and ideally, it continues forever (captivate you).
It may strike you, in case your hopes/wishes are not fulfilled or you're frustrated.
This may be the case especially if you're weak (if you're not in a good situation because love always consumes resources, most notably time).
I strike you so that you will never forget me could also mean, that you never forget the one who broke your heart.
The arrow may be a metaphor for Amor's arrow. When he shot it, the target falls in love immediately. The arrow actually hits you deep in your body -- directly in your heart.
If that cracks, it makes a sound. Alternatively, you make the sound by crying about the love you may lost or may get. Whatever.
Come get me before your life runs aground is a little bit weird for me. But it may mean that you should try to get someone to love before you die (run aground ?).
