Just feel so alone!!

I’m 15 weeks pregnant and I just feel so alone in this pregnancy it’s my first time being pregnant and all of my fiancé’s family are just being so negative :( his sister in law is jealous as she can’t get pregnant even tho she already has one child and is just making my life hell shes making me out to be such a horrible person because I’m loving my own life I just don’t know who to turn to anymore :( it’s making me doubt wether I want to be in this family at all 😥sorry for the rant just felt like needed to get it out
