I don't understand...

I will never understand why mothers that don't deserve to be mothers, or mothers that end up aborting or giving their child up or whatever, are able to reproduce but people that want for a baby so freakin bad can't get pregnant. People on the news throwing their children in dumpsters, I've seen a family leave their child behind in a Target and just left this newborn baby in a random aisle, people killing their poor innocent children, but for some very messed up and crazy reason someone that is going to give that baby everything, can't even have one. I know I sound bitter and mad, but I am. I want to do the one thing a woman is supposed to do, and have a baby. I'm tired of getting my hopes up every single time and then watch them get crushed. I don't know how you women that have been trying for years can handle the heartbreak every cycle. I'm only going onto my 5th cycle ttc and I am so depressed already. I'm already at the point to where I just want to give up. Ugh.
