it’s following me

V* is everywhere around me lately. My 7 year old stepson v* because of acid a few weeks ago. Then he got strep and v* for a week. Then my 5 year old son got it and projectile v* on me and the floor in front of me. Then I went to work a couple days later and my client v* right next to me. Now my stepson is sick again. The doctors said non infective gastroenteritis but I think that’s bs because they didn’t take a culture so they wouldn’t know. He’s been v* since 5am. Stomach bile. No appetite. Dehydrated. My husband had to take him to the hospital for fluids. I’m terrified.help me.
