Does anybody else feel like they are in a constant cycle of anxiety? For me, mornings are the worst. I struggle with stress headaches until around lunch time. After I've done some exercise my anxiety is much better. The evenings are ok but then it's back to feeling rubbish for a few hours. 

I often wonder if it is anxiety or if I'm just in some sort of habit of feeling rubbish/exercising and then feeling better. 

Is anybody else trapped in the cycle? Has anybody ever managed to break the chain?
