Hi, sorry to hear about your troubles but you need to provide more details in order to decide an effective treatment plan for you. If you’ve been having these problems for last three days only, we might want to look into what triggered it? But if it’s a long-standing problem, then the approach would be different. In any case, mindfulness and relaxation exercises as well as sleep hygiene would target both your anxiety and sleep issues. 1) Regular sleep and wake timings 2) Walk outdoors for twenty minutes twice daily : before breakfast and after dinner 3) No daytime napping 4) No caffeine and nicotine past 4pm 5) No screen time 2 hours before bed 5) Early dinner and gap of 2hrs between dinner and bed time. 6) Take out some time during the day to think about your active problems and how to tackle them, in order to prevent those from coming to mind when you put your head to sleep 8) Warm glass of milk with chocolate or a banana before bed 9) Bed-time routine which may include deep breathing and meditation, reading a book, lighting scented candles ( remember to put those out before dozing off ) 10) Some evidence in favour of using lavender oil on your pillow or in your diffuser to reduce anxiety and promote sleep 11) Over the counter melatonin 1-3 mg one hour before bed might also help
