Welcome to HealingWell Luna,In order to get to sleep more easily, you can try changing some of your pre-sleep habits to decrease your mental and physical stress levels. Habit-changing takes time and persistence, but if you stick to these changes you will find yourself adapting and feeling less anxious overall in no time.
Deciding on a particular hour that you want to be in bed by will relax your body by providing it with a comforting, familiar routine to follow. It will also train your brain to get tired at a certain time of night, which will help you fall asleep sooner after you lay down to do so.
Once you are lying down in bed, try relaxing your body one piece at a time. You can start wherever—your toes, for example—but relax each toe individually. Then move up to your ankles, your calves, your thighs, and so on. Make sure each part is thoroughly relaxed before moving on to the next. You may start to feel tingly and almost numb. This is good: it means your body is getting ready to sleep. Once you are completely relaxed, focus on breathing comfortably until you fall asleep.
I also have a mantra I used when the "worry" tries to creep into my mind - "My bed is for rest; not for worry"
Kindly,
Kitt
