Jealousy.....

Is it bad that I get super jealous when I see younger girls like 15/16 saying theyre pregnant and it wasnt expected and they dont know what theyre gonna do about it and all kinds of stuff. Like im 24 yrs old and still ttc how the hell does a 15/16 yr old get pregnant and say the baby isnt wanted or whatever when me and all other women around the world are trying so hard to have one? It pisses me off and I get soooo depressed when I see other women getting pregnant & I cant! I feel like I'm not even a woman...... I wanna curl up in a ball and cry all,day
