Struggle functioning when things going on

Hi,

Does anybody else struggle functioning when stuff is going on?

My mum’s been diagnosed with a severe lung problem that affects her breathing and now most days she’s exhausted and you can hear her struggling with her breaths. Since all this happened I have utterly and completely exhausted. I’m in my mid 20s and I’m always fatigued. If I do something I quickly run out of energy and it feels like I have the flu. I can’t even stay up later than 10pm. Too tired.
It’s just frustrating.

I wonder if I’ve got burnout. I had it once before and it felt never-ending then but now this time it’s really grinding me and I feel like this is more than burnout or maybe just worse than before. I wondered if something else was going on with me health wise but my bloods came back to the GP last week and everything is fine so they’re saying it’s autism/anxiety/burnout.

Looking back I see how I function mostly well but as soon as something happens I struggle to function then. Just wondered if anyone here is facing similar.
