Feelings are like the weather and will change; sounds like you are having a dreary sort of pattern this week :-) I try things that usually help, like finding/reading a good book or wandering around "observing" and thinking deep thoughts for a bit. Sometimes it turns out I'm just recharging my battery and an idea of something I want to do will show up. Making sure I'm going out each day and talking to a live person (not just radio/TV), even if only at the convenience store, helps.

If you are feeling a bit down, think of one little thing you want. I was in the middle of the zoo by myself and decided I wanted an ice cream cone and this was back before very many Baskin Robbins and I was in a place that didn't have any other outlets and it was a Sunday afternoon I think, back when things were closed on Sundays. I ended up having to go to the grocery store and get ice cream and my own cones and making a whole production of it but I got my ice cream cone! and ended up proud of myself and out of my funk. Just "doing something" doesn't matter what can sometimes help.
