Devastated

I'm 19 weeks pregnant and today at my sonogram I was told my baby's insides are growing outside of its body. The survival chances are slim to none. This is my first child and I really can't stop crying. They gave me the option to terminate the pregnancy or to continue. How ever I have 2 weeks to make a choice. I just felt my baby's first kicks this past weekend and idk how to express or explain this feeling. I would of never in a billion years thought that this would happen to me. Everyone keeps saying I'm only 22 years old and that I'm still young so I can always have another one, but it will never be the same. The empty space will never be filled 💔💔🙏🏾🙏🏾🙏🏾😢😢
