Feeling jittery

Feeling strange this morning.  Slept on/off yesterday but as I sit here I'm shaking internally and feel "jittery".
Just took my meds so maybe that will help, but I've noticed the last week or so I've not been "right".
Doc added a new med yesterday so maybe that will start to make a change.
All I know for sure is I'm easily overwhelmed and fall into meaningless rabbit holes.
Wouldn't be so bad if I would actually accomplish something when I did so but I just spin my wheels and accomplish nothing.
