It hurt so bad

I always read posts about how painful it is when someone else gets pregnant when you have experienced a loss or when you are ttc but just dont get pregnant. Well, tonight, I felt that pain. I went to the ER with my brother only to find out his gf is pregnant. They are far from being prepared to have a baby. Although I am happy for them, I am devastated for me. My SO and I planned our 2nd but at 12 weeks lost what wouldve been baby #2. It was so traumatic and one of the worst experiences of my life. I walked out of the hospital and immediately broke down. I asked why them and not us. Why was our blessing taken a way? It just hurt so bad. I bawled all the way home. Now I understand, that bittersweet feeling. I wasnt ready for it. I just dont understand although I try to hold on to my faith. I felt so defeated, drained, and exhausted. Now I understand all those women. I get it now.
