I know rational and irrational sides and those chaotic conversations. Drive me mad! you sound really frustrated to have to deal with all of this. Have you tried breathing exercises? When I start to panic, I tell myself to relax, you cant panic and relax at the same time. i tell myself that over and over again. its a bit chaotic but sometimes i win and break the cycle.

i related to your dental anxiety there. any chance of getting the work done without the shot. i have SEVERE dental anxiety and my last filling i asked him to try it without the shot and it went so much better. the shot usually hurt worse than the drilling did.

well i hope that rational wins for you and gives you a break. sounds like you deserve it.
