I have a dentist appointment in a few days and its been causing me SO much stress. I've been having issues falling and staying asleep, all my dreams are dental nightmares, my memory is horrible to the point where I can't recall the previous day and often think IRL events were dreamt up. My eating habits are fucked too, I'll either go too long without an appetite, or I'll binge to the point of pain and nausea without really realizing it.

Heres the problem though. The dentist is SUPER nice, I'm only getting a single cavity filled, I'm not scared of the numbing needle, and I dont have any issue with metal in my mouth. 

I truly don't have any of the generic dentist fears of like gagging, or fingers in mouth, or numbing needles, or whatver it is. 

I'm barely living from anxiety but I don't fear the dentist and I dont know what the fuck is causing this anxiety. I know its 100% this appointment causing me anxiety, but  theres nothing about the appointment that's logically scary to me... So like wtf?
