How to deal with jealous family members

Okay so I added this anonymously because a family member has this app and God forbid she knows I said it or all hell will break loose. But seriously. How am I supposed to deal with her about me getting pregnant before me. She was trying before me and now she's had an attitude and has been ugly to me because I am pregnant and she said it's not fair. I can't help hat she isn't pregnant. I want her to be and I pray for her daily. But I mean she is rude to me, she's jealous, and I don't want to be mean to her but dang. I mean okay she won't listen to any of my advice or her Drs. For one she isn't even in a stable environment she doesn't have a job or a vehicle for apts she doesn't take any type of vitamins or anything to help her body get in a better state to get pregnant she I severely over weight and won't do anything but sit on her ass, and I'm past the sympathetic point. Please give me suggestions on how to handle her. Because avoiding her isn't an option when she lives with us. And won't get out on her own.
