I don't know what to do anymore

So I'm currently living with my parents and I'm pregnant. I plan on getting my own house at the minute financially I can't afford it. But my mum goes in these moods I just can't bare them she will take a mood with me for afew days (3 days atm) an give me silent treatment or say slide comments. She's been like this from as young as I remember but now I can't deal with it. My boyfriend doesn't like her because of how she can treat me he said if she keeps this up she won't have nothing to do with the baby and he wants us to move to London where his family live and 500 miles from my family. I just don't know what to do I feel I shouldn't be put under this much stress
