Your mind is not at ease. Need to learn how to relax or distract it ..
For me, I find that distraction is the best way. Create a fantasy in you head. A story, complete with all the details. Think of your best dream and weave an intricate plot around it. Like writing a book about your fantasy life. It can carry over from one night to the next, and on, and on.
whats wrong with you is youre in the uk, here its only 240 so youre just up a lil late, haha.
