Make sure you are taking breaks!Plan to do fun stuff with friends after a couple hours of revision so you are motivated.Something I always tell myself is "this too shall pass".Remember even if you feel rubbish and stressed now you have a long holiday to look forward to after GCSE's to do whatever you want.I have A-Level exams coming up after half term and I am too incredibly stressed right now! Always remind yourself that eventually the exams will be over and you won't feel stressed anymore.
