A good simile for "crushed" could be "like a delicate flower under a heavy rock." Just like how a flower may feel overwhelmed and flattened under a rock, a person can feel emotionally or physically crushed by difficult circumstances. Remember, even when things feel heavy, there is always a way to bloom again with time and care.
