I haven’t been diagnosed with anxiety but it runs in my family, every day for about a year now I am nauseous all day especially when I know I have plans for the day. I’ve been to the doctor 5 times to see if I just had stomach issues but test after test show nothing wrong which leads me to believe it might be anxiety, but I’m not going to self-diagnose. It started when my cousin who was living with my family had a psychotic break and ever since then I’ve been scared I am going to see her out in public and be reminded of that night. I told the doctor about this but they dismissed it thinking it had no correlation but I really don’t know what to do because I have in person school tomorrow and I’ve been nauseous for the last 2 days every time I think about it. Does anyone have any advice or coping mechanisms? 

Tldr: I’m nauseous everyday from what I believe to be anxiety does anyone have any advice on how I can control it?
