Tampons !?!?

Natalie
I asked my mom if I could try tampons when I first started my period(im a virgin) she amediately said no because one of her friends daughter died from wearing one for to long ( the syndrome thing you get for wearing them for to long) but I found a couple in my moms bathroom and I tried it and it hurt like a mf! I couldn't put the whole thing in bc it hurt !? I don't know if I did it wrong or not but I'm more comfortable with pads but I hate walking around in school scared that people might see my pad and I'm always paranoid and asking my friends if they can see it ! I would rather just wear a tampon so no one can see it and soon enough I will have to bc of track and summer coming up!? Any tips on asking my mom if I can wear them now ??? I'm nervous on asking her im not that comfortable or close enough to. Just blurt it out and ask her!!!
