current events and other depressing things

Usually, right after I get into bed (following my bedtime snack of warm milk + toast), I reminisce about occurences of the past and/or fret about the future. For some strange reason, as I lay there, helpless and alone in the dark, all of life's problems seem to escalade into a boulder of problems. It's really frustrating, actually, and is probably the reason for my ever-present sleeplessness. Usually, I settle my restless mind by the conclusive thought that I really cannot change things through my worries. I can only give myself another ulcer/cold sore.
