General sense of feeling unwell 😷😷

I'm 28+3 pregnant and last night I had over 8 hours sleep, I've had my breakfast and a bit lunch/dinner with some snacks. I did have an emotional breakdown earlier over my failed marriage cause of my abusive ex husband but now ... A couple of hours later I just have a general sense of feeling unwell.

I feel exhausted and drained like my sugar levels have dropped, its really generally hard to explain but you know your own body and what I'm feeling right now.. Doesn't feel right.

It reminds me a lot of the feeling you get when your body has overcome a bad cold and it's left you feeling weak and exhausted, anyone else been like that ?
