I've been moving constantly over the past 5 years and I almost always miss aspects of the previous state/city. I'm not sure why I like to move, but i do. I've been depressed a ton in this current location, so I wanted to move again, but I realize I'll just get depressed in the next place and idealize the last one (where i currently am). So I know how it is.
Hope you feel better soon.
And don't beat up on yourself for being in bed. If that's all you can handle, so be it. Ride it out.
