I’m 14 and still cry after getting flu shots

I used to cry over these kind of shots, but ever since I got my Covid vaccine, I've been able to more overcome and be brave enough of needles

Those needles are tiny compared to blood needles. 22 times I've donated.

What do blood donation needles feel like when compared with the needles used to take blood samples for cholesterol testing?

Probably the same length and girth, honestly. Blood is thicker than whatever flu vaccines are made of, after all. As for the blood sample thing, I imagine a blood draw is significantly quicker than donating blood, since it's only a couple of vials as opposed to a big-ass bag.
