I can fully understand where you're coming from and while it can be rough, this can be a time of unique creativity for you. What I do when I'm down is I start planning the next phase. I'd recommend getting as detailed in your mind as possible. See the project coming together and not only will this be a great use of time you'd otherwise spend in bed, seeing this vision can snap you out of your funk. Works for me. I wish you the best. Take care. :)
