so annoyed!

My sisters got two children who she never even has. Always palms them off onto their nanas and when she has got them she does nothing but shout and scream at them. She can't even be bothered to take them to school half the time! She fell pregnant 6 month ago and got rid of it and she's just fell pregnant again even though she's saying she doesn't want anymore. I'm so annoyed and disheartened! Why do people have children when they don't want them!!!! I've been ttc for a year now after having a miscarriage and nothing seems to work! Urghhhhh 😭
