Really need to vent

I really need to just let some stuff off my chest I just found out a couple of weeks ago that I'm pregnant with our 3rd we'll have 3 under 3 with my pregnancies I got really sick an almost died having my first baby my second went a lot more smoother but still had its difficulties. Well I decided to tell my parents an my sister an now none of them want anything to do with me my mom told me to go fuck myself an that she hates me an that she doesnt care about me that she just cares about her grandkids my dad told me to stay away from him an his family an my sister didn't say a word to me an they all said that I was a selfish self centered narcissist an that what the fuck was I thinking having another kid an that I'm going to die an that me an my fiance aren't even married an that we live with my fiances mom the only reason we live with her is because at the moment we're saving for a home an we are also here to help his mom she had a tumor in the back of her head an she needs alot of help with alot of things we pay for all our own stuff rightfully so... that being said my parents an my sister live with each other because they can't affored their own homes I have NEVER EVER NOT A SINGLE TIME. Have asked for anything from them not for me an specially not for my kids I've never even asked for them to watch my kids an in case anyone else is confused as to why they spoke to me that way or wondering if theres more to the story theres not they are mad because I'm pregnant again so soon an because it's bad for my health I 100 percent understand that there WORRIED but to tell me to go fuck myself an that they hate me an to stay away from them just it doesn't make sense I can't wrap my head around it they have always been like this with me an they always come looking for me but I feel so numb to it all an all there bullshit is it wrong for me to just go on with my life as if they were no longer alive my parents an sister are never ever happy unless I'm living my life the way they think I should I'm just sick of always having anxiety wondering what they're going to think about my choices in life like my kids name's buying a house an in what city just its always in my head an when there not in my life I feel free I feel like I can breath I don't have anxiety... Sorry it's so long just had to vent alot I guess
