Ouch! You might want to go down another size just to take the pressure off your ear, which will reduce the chance of it forming scar tissue. Honestly I think you'll be fine once everything heals. Keep doing sea salt soaks and when it heals up, do daily oil massages. I don't think one little mishap will ruin your ear forever, especially since you took the right steps by removing the tape instead of trying to keep stretching anyway like some people would.
That's why I've never used tape; it always felt so tight and rough in my ears and I was always afraid that would happen if I left it in. A lot of people swear by tape but I think others just weren't meant to use it!
I have 1/2" lobes and 11 piercings: left helix x2, both conches, both nostrils, septum, navel, and VCH.
My lobes are small but I know a lot about stretching and how to do it safely, so message me if you have any questions!
