Also i tend to only get anxiety at night, evening, or late afternoon. I tend to get anxiety thinking of going to bed but then suddenly feel better once in bed and laying down. I sleep over 10 hours a night and sleep really well. When i wake up i have no anxiety and feel peaceful laying in bed after waking up. If i take a nap mid day it doesn't usually prevent night anxiety. I dont have anything in particular im anxious about other than being anxious about feeling tired or uncomfortable.
