An advice to muslim women of this generation
Tie your camel and trust Allah, yaani, do your best and then leave it to Allah; in this case, doing your best would be ensuring that the man you're marrying is God-fearing and upon the correct manhaj, so that he fears taking away your rights from you. After that, you should complete your Islamic obligations towards your husband and trust Allah. Remember that your Islamic obligations towards your husband are also ibadah, and is ibadah for the creation or the creator? Of course, the creator's right, Habiba? Don't think like this: "I need to study/work in case so and so happens." Have good expectations from Allah; Allah won't disappoint you.
Working or studying in duniyai matters is not forbidden, of course; however, you should not give it such importance that, to obtain it, you put yourself into haram, like co-ed schools, free-mixing workplaces, or taking riba for college, etc.
Allah has made men the caretakers for women, so there is nothing wrong with depending on your male relatives in this duniya to provide for you financially, as Allah has given the men this duty. Do not take it upon yourself when there isn't a need. Have patience and trust in Allah.
