Emotional wreck! 😢

We have been TTC for 6 months now, and it's something we want so bad! Today I took a test and it came back negative, I lost it. I couldn't stop crying, every second I get to think I make myself cry more, and even to the point where I see a pregnant women and my eyes begin to water. Am I the only one who's like this? Is there something wrong with me? Why can't I control my emotions today?
