Emotional toll

My husband and I lost our first pregnancy back in June. It was very hard on both of us, but we decided to try again right away. I’m currently pregnant again at 5 weeks. Has your pregnancy after loss taking a huge toll on you emotionally? I feel like I can’t be excited over it or accept it. Because all I can think about is it happening again. I know this should be an exciting time for us, and we should be celebrating this blessing. But I can’t .... I’m too crippled with fear. And I don’t know what to do about it. Or if there is anything I can do.
