It sounds to me like you have some serious anxiety about something or many things in your life right now.
Keep a journal by your bed. Before you’re ready to go to sleep, write down anything on your mind that is troubling you, anything unfinished you need to address, your grocery list….really anything filling up the worry center of your brain.
If you can, regularly set up 10 mins per night to do meditation to release some of your stress load. (you can find some great 10 min meditations on the web for free, or download a free mp3 one)
If this continues after you try the above, then I suggest a visit to your physician. He/she can evaluate you to see if you have signs of sleep apnea, or high blood pressure, or don’t know your age menopause, etc.
