does my tongue look normal?

Every few months (sadly), My anxiety like to fixate on a specific symptom or part of my body that looks slightly different and stress out for days upon weeks ab it. This time, it’s my tongue which i’ve noticed in some light looks blueish? but with flash it looks pink. Another problem i noticed was that dot/indent in the middle? I’m just afraid it’s something bad medically that i’m not gonna catch in time. Please let me know 1. if my tongue is normal, and 2. If you used to be like this or have advice on how to stop with the fixating and anxiety cycle, please let me know!
