MAD/PISSED/FRUSTRATED/ANGRY

So I just found out my sister in law is pregnant. That's fine and dandy EXCEPT she already has two kids with disabilities, she does heroin/pills/whatever, smokes cigarettes, neither her or her husband have driver's licenses, she doesn't have a job........ And here I am worried about if I'm taking the wrong f'ing vitamins while TTC for the past year!! And this bitch is pregnant again! And the family is so happy and excited...... It's like do you not get she's a f'ing drug addict?! I feel so alone. My husband says don't worry our time will come..... But when?? And why are drug addicts getting pregnant and I'm not?! I'm a good person. I don't do drugs, don't smoke and have a career. This isn't fair!!! 😠😠😠
