Thanks for making this. I thought I was the only one who would get extremely uncomfortable whenever anything goes down there. I won't go into details about when I was trying to learn, but let's just say I only use pads. All the same, I think it is more critical in performing than in practice to use a tampon. If I were you, I'd talk to my dance teacher to see if it would be possible to be able to use pads (and wearing a dance skirt) as an alternative. Especially if you're comfortable talking to her. I don't think that after being abused for so long, you should be exposed to such a strong trigger, especially if you happen to be on your period during a performance (although I don't know what you'll do then unless you wear a skirt or are exempt from participation). Also, you should look into getting referred to a counselor by your doctor or talking with your school counselor if your comfortable with that. God bless and good luck with that!
Just because everything's changing
Doesn't mean it's never been this way before
All you can do is try to know who your friends are...
