Mother disappointed I'm pregnant

My mom is not happy I'm pregnant at all. I'm 22 years old living with my boyfriend and have not finished college yet. I just told her this week that I am 7 weeks pregnant and she instantly began to say all these negative comments. Saying that me and my boyfriend both have suck ass jobs and there is no way we are going to be able to provide for this child. She said my boyfriend will eventually leave me and I will be a single parent with no way of taking care of my child. She even said that I am now a typical ghetto girl that goes and pops out kids without being married. All this negativity is just really getting to me. Now she's saying she's depressed and has failed me as a mother. I love my mother me and her have always been close. I knew she would not be the happiest about this baby but she's just going a little over board to me now.
