Help!!!!!!!!

Why do my nails Look so white. Instead of looking pink, they’re looking white. :( I’m so stressed out now. I read it can be signs of problems with your heart or your liver or poor oxygen circulation.They also have a purplish color to them instead of pink.

I’m so stressed out now....

How would I test to know I’m good in oxygen circulation??? And heart and liver.... does bloodwork tell you your heart and liver are good. Had routine blood work done beginning of the year and all came out good?? But don’t know what was checked exactly. Help!!!!

All my nails are starting to get this white patch on them. And I’m really stressed over it. And not every nail has the half moon on the bottom.
