Hi all. Really need some input here, especially if you have Bipolar (specifically type II). Two days ago, my partner (who has BPII and currently unmedicated)'s mental state took a nosedive; he's now fighting a deep depressive episode. When this happens, sometimes physical symptoms manifest that look like a cold; but most of the time he's just a little extra sleepy and a little more anxious / in despair.

These last few days have been a little different. He's been dealing with a stronger sense of anxiety; he's mentioned dizziness and lightheadedness when standing (sometimes seeing spots), and his heart rate soars from 80 to 140-150. No chest pains / numbness in the left arm though, so it's not the big one.

My question is whether or not (as a general, non medical opinion) this is POTS, and if a bipolar depressive episode is causing it. He's not really felt like this before, nor have I seen him feel this way before.

Any input would be greatly appreciated!
