I have always had trouble sleeping. And I always though it was because of anxiety. I would have trouble falling and staying asleep , but I was able to rest, and take small naps. I had a period of time when my sleep was just normal… But lately I am not able to sleep, at all. I think that in the last 3 days I probably slept less than an hour all together. My anxiety increased a lot in these days, and I have a huge difficulty concentrating in anything. I don’t know if the anxiety keeps me awake or if the lack of sleep keeps me anxious… Is there anything that could be causing this?
