That is a classic work related stress scenario. You do not need to be on medication to be signed off for as long as it takes to recover your Mo Jo. Write it all down for the GP as you will always forget bits then answer the questions truthfully. You will do yourself no favours by trying to be brave, if you cry that is OK they see it rather a lot. The most important person in this is YOU!!!!
Been there, got the T-shirt Sadly twice and it was 3 months off both times, work got majorly bo**ocked and told to improve many many things Occupational health were involved by me demanding it. Hope you feel better soon but make you your number 1 priority.
