Then maybe getting out of town, even before September, would cheer you up a bit? I'm a road trip person; I love that kind of thing. Maybe you could get away for the weekend.
Or DON'T get out of bed. Sleep in and read. If it makes you feel better--wasting time can be a complete joy.
I think you have to treat the depression very seriously, though. It would be a good thing if you had a doctor who would spend time talking with you about it. If you feel that you were over-medicated before (and I have to admit that I'm a convert to anti-depressants), you might want to take a look at the book, The Feel Good Handbook (author is Burns, I think?), which has been a big seller for years, for good reason, and suggests sensible ways of working through depression.
I know those blue days. They make you feel helpless. You can be absolutely convinced there's no hope. Sometimes it helps me to think: well, it's some wiring short-out in my brain. The gloom I'm seeing is not how things ARE. It's my perception at this moment. A day from now I'll be completely happy--yet nothing will really have changed, except me.
I hope you'll arise from that bed (don't know what time it is there) and check on that horse. I've totally worn myself out blabbing advice I hardly ever take myself. Hope you get to feeling less blue!
