She lives on the west coast of Ireland, and schlepped all the way to Glasgow to meet the dude. (That's in Scotland.)
Black made the brilliant move of going to Ann Summers, a sex toy and lingerie store in the UK, to both make herself feel better and make the boy jealous.
After quenching her thirst (in the beverage sense), Black went and satisfied her craving (in the food sense).
After the sundae, Black went home and showed off her new purchases.
Black's story was shared more than 6,000 times, and she told The Mirror that the dude has since apologized.
Black blogs about her life with bipolar disorder, and says that the date with herself turned out to be an empowering experience.
"For the first time in months I was able to go out on my own and feel like a normal girl – something I can rarely feel. I felt brave when I ordered a drink, as silly as that sounds to you, and I felt poised and attractive in my new lingerie," she says.
Hitting at the trolls on Twitter who have been bugging her after the post went viral, Black says, "I felt like a real girl, not the ill girl. So please don’t take my positivity away."
