Obsessed about my spo2 and 6mwt. 6mwt?

Four people in my home got RTPCR positive last month and I had mild headache and fever below 100F but rtpcr taken before symptoms returned negative yet took meds suggested by doc who suspected covid. My family members were suggested six minute walk test and I too started doing it even when I was not sure whether I had corona. I have Obsessive compulsive disorder and it is now playing with my mind now. I can't stop doing six minute walk test because I'm obsessed about my spo2 levels and anxious that I might have happy hypoxia. I'm anxious I'm asymptomatic and I might have happy hypoxia and if I don't do six minutes walk test, I might not know it and die at home. Should I stop checking spo2 and stop doing 6mwt? I'm worried that I might continue doing this till end of this pandemic
