Ok definitely invisibility.
If you're the only one who can fly, you will become an oddity that attracts attention. (PTSD girls nightmare!!!) so you'd have to keep it hush hush, fly in private, etc or risk attention, being scrutinized, and losing all privacy.
Invisibility being a dream coupled with flight being a nightmare, gotta go with invisibility. I value my privacy above all else so aside from moving to the middle of nowhere and flying only when no one can see me......gotta go with invisibility. What good is a superpower I have to hide and rarely use?

Feeling invisible is different that being invisible. Just ask mindy! Lmao.
