Happiness is like a butterfly; the more you chase it, the more it will elude you, but if you turn your attention to other things, it will come and sit soflty on your shoulder.
You're not scared of the dark, but what's in it. You're not scared of heights, you're scared of falling. You're not scared of the people around you, but of rejection. You're not scared to love, just afraid of not being loved back. You're not afraid to let go, you're afraid to accept the reality that he's really gone. You're not afraid to try again, you're just afraid of getting hurt for the same reason.
You can spend minutes, hours, days, weeks, or even months over-analyzing a situation; Trying to put the pieces together, justifying what could've, would've happened if you did something differently, or you can just leave the pieces where they lay and move on with your life.
