Act one, is a pretty long act, with lots of things going on. In the beginning of the act, we are introduced to a character named Nora. In my opinion, Nora is not really all that mature, and mainly relies on others to help her get by. Her husband, Helmer (Torvald) has a job at the bank, so Nora relies on him more than anyone. The way Helmer treats her is like a little child. Basically, he treats her like a baby. Another example would be that he refers to her as "his little skylark."
I guess you could say that Nora doesn't really have the easiest life, but she has no one to blame but herself. In trying to fix all of her problems, (as John said) I feel like she's digging herself into more and more trouble in the first place. Also, being that she is trying do this all without her husband finding out, that doesn't help as well. So if you think about it, Nora really has no-one to blame but herself.
