To young but why?

I recently just found out that I have can't have kids. Most of my friends say that it's for the better cause I'm 20 but I love kids &I want some of my own but I can't have them :( 
I've learned to deal with the fact that I can probably have one but it will probably take forever. 
Today at work this girl went in for a pg test & it was positive but she actually told me straight up she wanted an abortion. Really??! I wanted to slap her then & there! Her mom was even encouraging her! I was so mad that when she left I went to the break room & started crying. I wasn't crying cause I was mad but I was crying cause someone is willing to end a life when it's a blessing. It just got me all depressed cause I can't have a baby but someone who can is willing to end it 😢
