Water Through A Sieve

Occasionally I go through periods when I find it too hard to decide on an outlook . Im not sure how or in which order to view a sequence of events . Do I group them into order of importance ? Do I put them in chronological order as a time line ? Or do I carefully examine each one and look for flaws and then arrange them as the most certain first , and so on ? This is my problem . Im cursed as I cant hold any idea mentally as the tide of my mind ebbs and flows . Can I reduce situations to one emotion as emotions are often unreliable . Only for a split second do I see the true essence of a situation before the water instantly muddies again . This is how it feels to be me . How do people exist with a " mindset " ?  I cant hold one for a second .
