Although I don’t have any fear of needles, I get freaked over insect stings. True, those really do hurt, but life as I know it wouldn’t be over if I did get stung. The thing we fear gets blown all out of proportion.
One good bit of advice I got early on was to treat the syringe like a dart. I think some PWD treat it like a gentle insertion and can feel the needle tip before actually pushing it in. By the time I feel anything, the needle is already fully inserted.
I joke with friends that after the first 100,000 shots, the fear goes away. For me, the bigger concern is forgetting that I took a shot and taking another. That almost never happens, but it has caused me to ponder from time to time. The whole process of determining dose, filling the syringe and injecting through my shirt is sooooo automatic.
