How to deal with mom making me feel bad about my pregnancy?

For starters, I’m 21 in a university and I graduate next year. I work and handle my priorities as best as I can and I also have a good savings account. The father of my unborn child is very active and present, we’ve been together for a while and we plan on moving together in 2 months.

My mom and step dad is constantly telling me I won’t be a good mother, I’m making a dumb decision and she feels as though I will be a burden on her with my baby which isn’t true at all. For so long she’s been very controlling and manipulative over my life. She constantly mentions how I ruined my life and it’ll only go downhill from here. She’s confident that I won’t finish school which is not true, obviously finishing my last year of college is a priority to me, it’s only ONE year left. Overall she makes me feel like shit and as if I’ve made the wrong decision. After she goes on a rant about me being a bad mother, she’ll call me and ask me how I’m doing and if I’m okay?? I think that’s totally backwards. I’ m definitely keeping my baby. How can I deal with the negativity? I honestly hate living with her and I’m counting down to the day I am able to move away.
