You are under a lot of stress and have symptoms of anxiety. Meditation, positive thinking, relaxation exercises and stretching will help you fall asleep again.
Waking up between 1 and 3:
Something is weighing on you emotionally. You need to forgive someone or someone needs to forgive you. Breathing exercises will help you continue to sleep.
Waking up after 5am, before dawn:
The energy comes from the gut and your body is sending you a message that you need to resolve the emotional state that is weighing you down.
