lamentations 3: Can the Lord lock me into darkness?

 In Lamentations 3 we read:

1-3 I’m the man who has seen trouble,
    trouble coming from the lash of God’s anger.
He took me by the hand and walked me
    into pitch-black darkness.
Yes, he’s given me the back of his hand
    over and over and over again.


we are used to read that the way of the Lord brings us to light; but here, it is the opposite: the Lord took me into darkness.

    
4-6 He turned me into a skeleton
    of skin and bones, then broke the bones.
He hemmed me in, ganged up on me,
    poured on the trouble and hard times.
He locked me up in deep darkness,
    like a corpse nailed inside a coffin.

even worse: "the Lord locked me up in darkness like a corpse inside a coffin".

13-15 He shot me in the stomach
    with arrows from his quiver.
Everyone took me for a joke,
    made me the butt of their mocking ballads.
He forced rotten, stinking food down my throat,
    bloated me with vile drinks.

16-18 He ground my face into the gravel.
    He pounded me into the mud.
I gave up on life altogether.
    I’ve forgotten what the good life is like.
I said to myself, “This is it. I’m finished.
    God is a lost cause.”

We are used to think that our Hope is in the Lord, but here, the prophet says that "God is a lost cause".
However, the prophet remembers that "It’s a Good Thing to Hope for Help from God":

    
It’s a Good Thing to Hope for Help from God
19-21 I’ll never forget the trouble, the utter lostness,
    the taste of ashes, the poison I’ve swallowed.
I remember it all—oh, how well I remember—
    the feeling of hitting the bottom.
But there’s one other thing I remember,
    and remembering, I keep a grip on hope:

In desperation, let me remember who the Lord is. One thing to remember: God’s loyal love couldn’t have run out,    his merciful love couldn’t have dried up.

    
22-24 God’s loyal love couldn’t have run out,
    his merciful love couldn’t have dried up.
They’re created new every morning.
    How great your faithfulness!
I’m sticking with God (I say it over and over).
    He’s all I’ve got left.

25-27 God proves to be good to the man who passionately waits,
    to the woman who diligently seeks.
It’s a good thing to quietly hope,
    quietly hope for help from God.
It’s a good thing when you’re young
    to stick it out through the hard times.

28-30 When life is heavy and hard to take,
    go off by yourself. Enter the silence.
Bow in prayer. Don’t ask questions:
    Wait for hope to appear.
Don’t run from trouble. Take it full-face.
    The “worst” is never the worst.

I am used to ask questions in the middle of suffering (am I the cause of all this?), but here, the prophet says: "don't ask questions, wait for hope to appear".

    
31-33 Why? Because the Master won’t ever
    walk out and fail to return.
If he works severely, he also works tenderly.
    His stockpiles of loyal love are immense.
He takes no pleasure in making life hard,
    in throwing roadblocks in the way:

55-57 “I called out your name, O God,
    called from the bottom of the pit.
You listened when I called out, ‘Don’t shut your ears!
    Get me out of here! Save me!’
You came close when I called out.
    You said, ‘It’s going to be all right.’

58-60 “You took my side, Master;
    you brought me back alive!
God, you saw the wrongs heaped on me.
    Give me my day in court!
Yes, you saw their mean-minded schemes,
    their plots to destroy me.

61-63 “You heard, God, their vicious gossip,
    their behind-my-back plots to ruin me.
They never quit, these enemies of mine, dreaming up mischief,
    hatching malice, day after day after day.
Sitting down or standing up—just look at them!—
    they mock me with vulgar doggerel.

64-66 “Make them pay for what they’ve done, God.
    Give them their just deserts.
Break their miserable hearts!
    Damn their eyes!
Get good and angry. Hunt them down.
    Make a total demolition here under your heaven!”


All the Bible teaches me to call to the Lord in the middle of my anguish. Am going to remember it? Hope so.
