Going through a stressful period at work with lots on and a massive project which will be ongoing for the next six months. I keep waking up in the middle of the night and can’t stop overthinking the same worries, mostly are things that haven’t yet even happened but could go wrong. How do you train yourself to stop this, as I know that worrying won’t do any good. It’s now affecting my day as I’m so tired from lack of sleep!! I try writing anything down to remind me to look into it the next day but it keeps going round in my head. I just need to switch off!
