It's been two weeks since I had a full night's sleep. I'm so fatigued, cannot focus on anything at all. I've tried a lot of internet hacks but nothing is putting me to sleep. I miss my girlfriend, she used to make me feel so peaceful but since she has been gone all our memories keep playing in my head and hence I've developed insomnia. My head is aching so much that it feels like it might burst open any moment.
