I feel you man. I've been in a similar vibe for a few weeks now. Forcing myself to push through and continue getting things done. It's not easy and it's not fun. I haven't been as productive as I should be and that means things are getting delayed or pushed back. I go through a phase like this almost every winter for some reason.
I find that sticking to a routing as much as possible helps getting through those tougher seasons of life.
Hang in there bud, you're a net positive in this world.
