Having an existential moment/how can there be 2 lady rainicorns?!

UGH UGH UGH, GT. I was looking on the mainpage, and someone has my name. Except theirs is ladyrainicorn, and that's her actual blog name while mine is something else because it's what I signed up on Jez with like 4.5 years ago. I'm SO devastated, you guys. I really am. I DON'T WHAT TO DO! HELP! It looks like their profile is new because their first ever post goes back to March 18 of this year. UGHHHHHHH!!11!!1 I don't want to have to change my display name >.<
