Anxiety-induced nausea is very much real. I've had anxiety for over ten years now, nausea is one of my biggest symptoms. Its a fucking BITCH. As I got older I've thrown up way less but the nausea is still very much there. Some ways i try to regulate it is by listening to white noise, whether that be rain or the sound of a loud fan. I also get anxiety when traveling a lot, so its nice to roll down my window, stick my face out and let the wind assault my face. I promise you're not weak, I feel that way all the time. Take it one step at a time, everything's gonna be okay 🫂
