Explanations

HOW CAN LIFE BE WHAT YOU WANT IT TO BE= Life can’t be what you want it to be. Life is not as you want it.
Notice the pronunciation of WANT IT. In standard BrE it is /wʌnt ɪt/ but in Ame, when the T goes after an N it may disappear, so here it is pronounced /wʌnɪt/ .

FROZEN= Below zero degrees (freeze-froze-frozen).

YOU’RE FROZEN= You are very cold, without feelings. You are not human.

YOU’RE FROZEN WHEN YOUR HEART’S NOT OPEN= If your heart is not open, you are frozen. The word WHEN sometimes has the same meaning as IF.

CONSUMED= Obsessed.

MELT= Turn a solid into a liquid. If you are frozen, you are ice. If I melt your ice you will have feelings again and become human once more.

BE APART= Be separate.

YOU HOLD THE KEY= The decision is yours. It all depends on you.

THERE’S NO POINT = there’s no sense = it’s no good = it’s useless.
Notice the preposition IN.
Placing the blame is useless = there’s no point in placing the blame. (it’s nobody’s fault)

PLACE THE BLAME= Declare someone culprit. To say that it is somebody’s fault.
It's more common to say "put the blame" and it always uses the preposition ON: Don't put the blame on me (= don't say it's my fault).

THE HURT= The pain, the sorrow.
