I was not supported in my childhood dreams because my dreams were not suitable for my family structure. Owing to the patriarchal structure of our society, women are not allowed to go outside

It is so quiet unfortunate that all what you dream up during your childhood never came in to existence .and there is also one important point that you mentioned that really made me happy that is not every dream that come to reality and absolutely that is true but with the situation at hand what come out way is but important that we embarrassed it and move forward so long as it can put food on our table .

Also the fact that your parents and your family could not support you or were not in support of your dream was another obstacle for your success but am glad your brother and sister are equally undergoing education and may be by God grace they might be favor and through them ,some of those dream could be fulfilled.
