COVID Anxiety

So recently, I thought I felt ill. I woke up from a nap the other day, and my face felt flushed, and I had a big headache. I also didn’t eat dinner, so I thought that may be the reason for the headache. I ate a pb&j sandwich, and ended up throwing it all up 30 minutes later. I have been so anxious these last 2 days about Covid. Thinking it’s Covid, and constantly googling things and reading things online. I have no cough fever or trouble breathing but I have such bad anxiety to where I think, what if I get those within these next few days. I’m a heavy woman. I’m 250lb and am considered morbidly obese so I am a high risk for covid. I’m just so anxious I wanna cry. I don’t know what to believe, or think. All I want to do is sleep the scaredness away. I want to get tested but then I don’t because I’m scared . I really don’t know what to do at this point. Please help with advice if u can
