PCOS & Jealousy 😩😖

End of January of this year I was finally diagnosed with PCOS of 5 years ttc. My husband and I have been married for 6 years and he has two kids from a previous marriage. I feel like 💩 for being jealous of them. I just want a baby so bad and they literally want nothing to do with me. Dont get me wrong I love them to death but their feelings just makes me stress even more. Been on bc for 4 months but the dr wants me to lose more weight (5'6 200 lbs). I feel like I'm not ever going to accomplish this journey. Is it normal to feel these emotions?
