Hi there.. .Sorry to hear that you are having trouble with falling asleep and staying asleep. That can be really challenging. And of course we all know how important it is for our bodies and minds to get a great nights sleep.
Not sure how long this has been going on for you, or if there are any other "underlying" issues (such as medical, anxiety, depression etc...etc..) So many factors can play into "Why" we aren't getting a good nights sleep. But, perhaps starting with some small changes could possibly make a big difference.
Examples: Shutting off all electronic devices ONE Hour "before" you're ready to lay down so it can help to relax your body and mind...... Perhaps taking a soak in a warm bath can get you relaxed...... maybe trying some warm milk, or chamomille tea.......Reading a book perhaps could help to relax you to the point that you start to get tired. There are many other ways or things that you could try doing if you haven't already.
If there are other issues such a physical/medical etc... perhaps speaking with your healthcare provider could help you get to the "root" of the problem. Sometimes even taking certain medications can interfere with sleep, or even certain "stressors". Be sure that all these things are eliminated or "lessen" first if this could the problem.
Best of luck to you moving forward. I have also "moved" your thread into the "Sleep Well" section here of our Subcom. This will ensure that its in a more proper place, as well, you may also get some other responses. Take care!
