At the beginning of the pandemic, i would constantly overthink about covid and getting covid. I barely left my house and i would clean constantly. I felt like I was starting to get better because my mind wasn’t racing as much and I got a little more lax. Recently, i’ve been isolating myself, cleaning more, and worrying. I find myself in a sour mood a lot because i’m constantly thinking about what could happen. Im traveling with my gf in a couple days and i’m petrified with worry. What if my covid test come back positive and I can’t get into the country?(the place we’re going requires a negative covid test) What if someone at the airport has it? What if I get it while we’re there? On top of my covid worry I have my everyday stresses and it’s getting extremely overwhelming and debilitating. :/ 
If anyone has any advice as to how to reduce some of this anxiety im all ears.
