Know that feeling. Been feeling it for a while now, but then I'll wake up and feel "fine" and think it was all my imagination. If I look through my posts and my journal, however, I know that's not true.
We are often close to the edge when not fully stable/on the right meds. Listen to your inner self...to what you really need to do to stay safe and well.
Hope you can get to feeling better soon. Maybe the beach will help.
