Why is my mom so insensitive? She is trying to bring an overwhelming pressure to bear on me. What can I do?

I'm unemployed now.I see it as a golden opportunity because I can take advantage of this unemployment period to learn something which I deem is very important to my personal growth. I'm still yong so I think I need to have a long-run life plan. However, my illiterate mom often calls me from home asking me to get a job. It is not wise to do that. Currently during this great economic crisis, many big companies are laying off their employees. It is difficult to find a job. And in this process, it will cost you much time and much money and much energy even you don't get one. I just keep learning every day,I work hard and I think I'm productive. I don't waste of my time, I make full use of my time. I want to improve myself and then get a job. Of course this process takes some time. My mom is so impatient. Her attitude is disappointing. She pisses me off. She is always nagging,I can't stand her.Why is she so insensitive? She probably wants me to freak out under an overwhelming pressure. It is not easy for me to settle down to learn something but she is just trying to make me feel fidgety. What's the hell with her? I feel I can't concentrate on learning now. On the other hand, it is so difficult to get a relatively good job. Does she want me to feel hopeless and helpless so she will be very happy? Is that her purpose to make me feel hopeless and helpless and therefore commit suicide? Why is she so brutal and cruel? How can I deal with this problem? She wants to overwhelm me, what wants me to feel despaired.She wants to disrupt my life plan. Help
