Seeking peaceful moments

I have been feeling disturbed recently. By what? Many things. But I think the culprit of it all is uncertainty. Uncertain of the future, the people around me, my life and myself as a person. The mind is in a whirlpool. The heart yearns for some peaceful moments. I'm tired. Tired of people's expectations of me, of my expectations of others, of the burdens I have to shoulder, of the things that are happening in my life, of the things that are not happening in my life. I have the sudden urge to go away. Somewhere far, where out of reach is out of mind. A selfish thought I know for we don't not exist for ourselves alone. How important is "I"? Rightfully, "I" should take care of myself, be my best friend etc for "I" am the most important person to me. Sounds self-centred but isn't that what self preservation is all about? Who will treat "I" better than myself if everyone has an "I" in them?
