Flopped my GCSEs

I've grown up in the environment of where anything below a 7 is a fail. I've been lucky enough to go to a good grammar school and struggled with the competition and stupid high levels of achievement. Yeah, I know it sounds like I'm bragging, but it just what it is.

I got my GCSEs yesterday, and got 8,7,7,7,7,6,6,6,5. I'm incredibly upset with them and feel like I haven't really got a good chance of getting in to the uni's I originally planned to (Cambridge, LSE, UCL etc). Those GCSEs are going to be seen as medicore when seen in context of my school as well. Not too sure what to do.

I've seen the 'are my gases good enough for x' but I don't really want to go on them as i'm seeing everyone doing so much better than me and having the same aspirations as me.

Just feel a bit crap as I was really pumped before results day, I was on a Cambridge summer school and had so much fun and thought Cambridge looked achievable if I actually put in the work 0 but now i feel so demotivated.
