Tomorrow is my first ultrasound and

I’m TERRIFIED!! I think I’ll be 8 weeks tomorrow, and if I go off my last period, I’ll be 9 weeks 3 days. We were TTC for a year and Finally got pregnant. It seems so surreal ! I feel like it’s all a joke and all those tests I took were wrong. Also, I worry if something is wrong ? I’m suppose to tell my mom, siblings, in-laws and 9 year old son next week! I’m just really nervous and overwhelmed! I don’t know what to do or how to feel at this point. The very few who do know say once I hear the heart beat I’ll feel better, but will i? All the what if’s keep me up and wonder if I should wait longer if everything goes well tomorrow. I never felt like this with my first pregnancy! I’m so anxious it’s sickening! Am I the only one ?
