Advice Please! :S

Firstly, take a deeeeeep breath. It'll all come right

Secondly, (you might not like this) GCSEs are not that important. Bear with me, you need to pass to get onto some A levels, and you need Cs to get into most post 16 courses, but they do not impact much after that.

Divide up your time, make a revision timetable and stick to it. Give yourself breaks, get a good nights sleep and do your homework. Don't stress yourself out about any of it - remember that your mental health comes first and foremost, anything else can be sorted later on

Don't panic, just keep it cool.

It's not too late to fix any issues that you're having with work. The first thing you should do is identify why your grades aren't as good as you want them to be. Is it that you don't know the content well enough? Do you think you should do more past papers for each subject? Are you putting in enough work at home?

Figure that out and you can fix it. Also if you have someone to speak to about it, like a teacher at school, then ask them for advice too.
