Bipolar and immune system/physical health?

Anyone else find that bipolar in turn impacts their physical health and immune system?

Just coming through the other side of a depressive episode this week and of course as soon as I start to feel better mentally, I wake up with sinusitis and a flu, and bed ridden because of feeling so terrible.

During the pandemic I was contracting COVID pretty much every 3 months and it’d take me longer to recover.

It feels like I’m sick every 3 months and almost always coincides with my episodes.

Any tips?!
