Expect spiritual direction given and questions answered, for your part you are expected to do what you are directed to do.
Ideally, your spiritual director should be a priest, but a nun is fine if she wants to take on the responsibility of the task - which often requires great patience on her part - in addition to gaining great trust in you that she is not wasting her time with you.
In times past, our parents were often our primary spiritual directors so really, if a priest is not available, anyone you trust who is versed in the faith and willing to help you works, but a good priest is always best, always first choice.
Go to confession. You can and should go often, especially if you're in mortal sin, if not in mortal sin, then this is how to handle that -
"Forgive me father for I have sinned, my last confession was x weeks ago. I do not have any mortal sins to confess father, but for all the sins of my past life, particularly for the sins of (here mention in brief past mortal sins, perhaps habitual sins of your past you've already confessed), I am heartly sorry, please forgive me father."
