To tell the truth she did not face a great deal of "hardships" but had to deal with some important problems.
She had married her little brother,whom she wanted out of the way and
found the occasion to do so through her relationship with Caesar. When
he was killed she was faced with the problem of keeping Egypt
independent and herself on the throne,she once again managed to do so by
her love-affair with Marc Anthony. When they lost the battle against
Octavian and her lover committed suicide,she knew it was over and
preferred to kill herself before being dragged by Octavian in his
Triumph procession in Rome.
She lived in luxury, was powerful,intelligent and attractive. Was loved
by two of the most powerful man of her time. I would not say that she
had a very hard life,only her end was tragic.
