It's normal peeeegeeeee.
Just your body doing what bodies do because we were made to be weird. To get out of it I try and be productive. Clean my room, do my laundry, eat some real food by making a real meal, not drinking on a Saturday night, doing whatever it is I've been putting off for whatever reason, or anything useful.

I felt a little down earlier today but then I decided to walk to the store instead of driving there and now I feel pretty good.
