FML THIS ISNT FAIR

i just found out my 16yo sister is pregnant AGAIN my niece was just born in July and she's already pregnant. I'm soooo pissed off ive been ttc for 3 years no luck and she gets two kids her little kid ass doesn't even deserve she can't even afford to look after. This is just jealousy and spite talking cause I love my niece to death but life is so unfair 😡
