I feel for you Sorrel.. sleep is important. Do you have a night time routine? Where before you head to your room, you put yourself in a frame of mind & body for sleep? Does a warm shower before help? Soft lavender scents (or other aromatherapy) also sometimes help. Is your room arranged in a tranquil way? With soft low lighting at bedtime etc. What is the energy in your room? Do you have clutter or is it in a well organised way (at least your room, you know?). Soft music beforehand can also put some people in a relaxed mood. Basically doing things slowly quietly as you set about your bedtime routine may help. Just ideas... Also, do you write or keep a journal? Sometimes the simple act of jotting down worries and annoyances can stop them running round and round in our heads. All the best to you
