Wow. Been there! 6 months of the worst stress and it got very messy cos I didn’t see the GP when I should. Still worked, stupidly, and ultimately got made redundant after I told my boss I needed a different job. Then followed a complete and unexpected career change at 45 and I’m loving it 6 years down the line.
The few people I spoke to at the time said you are not alone. I felt very alone as I couldn’t find anyone who was or had gone through the same.
You’ve done a great thing opening up on here.
Get to the GP quick, get signed off and see whether meds are recommended depending on your current symptoms.
You’re going to need to change that job but you can deal with that later, for now, getting sleep and health sorted is no 1 priority. Don’t get that sorted and will get even worse trust me.
If you want to PM me I’ll happily give you my number for WhatsApp or phone chat as it’s a bit clunky on this forum.
