I suffer with insomina sometimes. It causes my anxiety to become worse. When I try to sleep, I think to myself. "I am going to sleep tonight, I need to keep thinking of nice things and I'll drift off and fall asleep". But when I know I'm not asleep, there's this big sensation of anxiety that I feel. It's not a nice feeling. If I know I haven't slept for two days or for a night, I think to myself that I'll never sleep. I sometimes have had trouble sleeping and I tried to sleep and the next morning I realise I have fallen asleep. I feel so happy when I have fallen asleep. I do think about things which I worry about before I sleep, but I tell myself. "Stop thinking about it, you need to sleep" and then I try to stop thinking about what is worrying and I think of being on a rollercoaster or something random, By thinking of something random or letting your brain drift, it helps me drift off to sleep.
