When my mom will come back?

1,2,3,4 day, a week, a fortnight or a month?
I lost my patience to wait already.
She always said I will be back tomorrow, tomorrow..
But she broke the promises.
Hopefully she will come back soon.
I cannot stand living in this quiet and lonely house.
I went maniac by non stop buying books
In order to forget the loneliness..
I understand her,
she need to take care her old dad,
who just underwent a leg surgery,
who was also a diabetic,
may took a long time to recover.
Just pray in the morning and night
that he can get well
and my mom will come back soon.
