I'm stressed out and when I try to go to sleep I can't shut off my thoughts. What should I do?

You could take a look at the sleeping well article that is under the self help guides here on 7 Cups of Tea, it might help you!

if you have an apple device, use the sleep well app. It will help you relax and fall asleep. it works beautifully.

when you go to bed, try listening to some quiet soothing music or some of your favourite music and lying in a cool, dimly lit room, i find this helps me when i can't sleep.

It may help to leave a notepad or notebook and a writing utensil near your bed, like on a nightstand. When you feel the stressful thoughts intruding, try writing them down. It can help you let go of the thoughts. If the thoughts are keeping you up because you feel you have to attend to them, assure yourself that the thoughts will be there in the morning, right where you wrote them, and that you can take care of them in the morning. Breathing exercises and meditation can help lots too - there are plenty of exercises for both available for free with a simple Google search!

When counting sheep and a glass of warm milk fails, there's a few different strategies you can take. Consider your sleep hygiene; is your bed a place of comfort and relaxation, or do you use that space for homework or to do your taxes? Do you shut off all sources of noise and turn off all lights before bedtime? Do you stare at bright lights, like that of a TV or cell phone before trying to sleep?

listen to music(light music), think of something happy, make thoughts about good things in the near future. sleep with someone else if you can. talk to someone that makes you happy before you go to sleep.

Try to write out your feelings, drink some tea, play some calming music, think of calming thoughts, and remember that sleep will help.

Make sure you're electronics and food are put away about an hour prior to your bedtime. In addition, I usually inhale for four beats and exhale for eight and I repeat. (I'm a musician)

Try to watch some videos on Youtube about the topic. Meditation, sleeping music...try it and see if it works :)

Count some sheep, listen to relaxing music, try some meditation methods, try sleeping in a very dark room to calm your thoughts and focus on your breathing! This is what I do when I can't sleep and my mind is busy, I really hope this helps~
