Because this seems to be a poem,
I may not fully understand what it is meant to say.
I also don't know whether you are following a specific form or meter.
Here is my attempt at corrections:
Is the grammar right?
As the day went on,
It is still the same,
Somebody is thinking of me/it(?); I am not sure what the object of this line is.
In the silent night,
The stars disappeared in the sky,
Somebody is looking up;
want to find some food,
But the fridge is empty,
I want to buy some more,
But only a few coins remain.
As you all know,
It is still the same.
