I combat it by getting diamazipan from the doctor.
The one time I didn't have any,when the assistant asked if there was anything she could do to relax me,I told her that when I was younger,my mum would always be with me stroking the back of my hand and reassuring me.
That's exactly what she did the whole appointment,thankfully,I was too scared to get a hard on from her touching and reassuring polish tones
