Trying Not To Cut My Mom Off !

I'm 24 Years Old And My Mom Was Diagnosed With Bipolar Disorder In Her Early 20's. Growing Up With A Bipolar Mom Was Stressful When I Was Younger And Til This Day It's Still Stressful Dealing With Her. I'm 16wks Pregnant And I'm Trying Not To Stress Or ANYTHING !! But My Mom Continue To Call My Phone Cursing Me Out Calling Me Immature And Leaving Nasty Vmails On My Answering Machine And Just Today In Particular It's Been Going On Since 9am NON STOP. It's Like If I Answer The Phone She Curse Me Out ! If I Don't Answer The Phone She Leave Vmails And It's Kind Of Getting To Me Now. Like I Love My Mom And I Don't Want To Feel Like I'm Turning My Back On Her But I Can't Put Up With This Right Now IM PREGNANT !!!! It Hurts My Heart That She Does This And Then Blames Me When We Have Our Periods Of Not Talking. My Mom Has A Lot Of Health Issues Besides The Bipolar Disorder And I Don't Want To Spend Her Last Years Here Arguing With Her Or Not Talking To Her Because If Something Happens To Her In The Must Of Us Not Talking Or Whatever Lord Knows I Would Hurt Forever !! I Just Don't Know How To Handle This Right Now 😢😢😢😢
