Mean rich girl and terrible birthdays

Natalie👑 • Well, I'm Natalie. That's all
Ima tell you all a quick story of my past and it's just quick because I feel like it was unfair 
So when I was turning fifteen (I'm seventeen now) I was the 8th grade loser and nobody likes me because I wasn't cool enough to be with other people, no one cared about me and of course I was bullied for being fat. 
So when my birthday came up it was on a Sunday and that day my middle school crush (now ex) he came by and teased me saying how I was desperate for attention and I kinda denied it so Sunday came by and I was pretty excited to turn fifteen 
I called my outside of school friend they all had made last minute plans so had my sisters friends, so  I had been stuck with one of her friends who was a rich kid and she had gotten me a 50$ gift card so that day was the hottest day of spring  95 degrees and in some places that's nothing but it was super hot. Now this girl she had forgotten her pills and were in this public place so she can't take them and when we're mini golfing at this cheap knock off of Chuck e cheese and we were five holes away from finishing and she complained that she wanted to go get some Olive Garden and then she said it was my birthday so they made a cake and of course I couldn't stay there because this girl was
'Tired' so we took her home and went home ourselves so what happened next was this girl had complained to my sister saying this 
"Look I wasn't expecting that your sisters birthday was that lame I've been to kids birthday parties that were better than hers. So never invite me to it Again. Okay?"
I found it later that day and that tied off my shitty birthday I cried that night and honestly it wasn't my fault...right I don't know I just needed to get this memory out of my head because it's been bothering me for a while
