Phobia measuring sp02. Online. please)

Hey, I am going to toughest phase of mine life. It is much tougher than covid treatment which I had got around  6 week( 25th Feb 2021). My ct scan at time of covid showed 40% Infection. I did x ray after one month( 25th March 2021) of treatment and it came all clear. I was not on oxygen support during my admission for 5 days.  Now,  I have developed fear of sp02 . I measure 50-60 times in a day. I have 4 oximeter to confirm reading.I measure after taking bath, after climing staiers ,after running for 6 min continuously, while seating incline, while lying down... My sp02 ranges different in different Position...sometime , it shows 96-97 and sometimes show 97-98. If it remains 98 then I feel good but if it gets below 98 , I start panic. I have read many things abouts lung fibrosis and same goes inside mine mind. I cry for an hour if sp02 goes around 95-96( sometime only). I am really stressed due to this... Please help( ready full and please not just reply to consult online.please)
