I believe I might know a bit of how you feel. That sense of tiredness ... related to "fighting it" was what I experienced today. Spent a fair amount of it in the bedroom, which is old behavior newly revisited.
The thing is- it's just another day gone by and there's nothing to show for it ... and time's not on my side. So I guess if there's anything I might write in order to "shape" this all a bit more positively- and to use your words- I'm going to "try just about anything" to mix it up tomorrow. Call someone, make a commitment, stay upright, write some, work on not being an *******. You know ... the basics.
