The tighter I hold

I think it's at a point where I know it, but the people around me do not, I am apparently extremely sensitive. When I learn to love something, and want to grab hold of it not wanting to lose it something always happens and it slips away. The traumatizing fear of people, things leaving me has left me with unknowingly pushing others away afraid if I learn to like them, I would never want to leave them and if they eventually do I will be hurt by it again. I am just, sensitive.
