Good morning! Sorry you're feeling a little blah. Are you taking good care of the other things that affect overall energy and mood? Getting decent rest, hydrating, eating well, and exercise? If not, force yourself to work on those and see if they don't produce an improvement.
Secondly, have you started to find ways to engage your mind and fill your time? I ask because the feelings you describe are exactly what I experience when I let isolation and boredom creep in.
Hope this is helpful! :-)
