post-viral fatigue and crashes after small tasks, does this sound familiar to anyone else?

i’m 22 and had a virus about a week ago. since then i’ve been experiencing this deep exhaustion and weird brain fog that doesn’t feel like normal tiredness. it’s like my body is constantly trying to shut down and even basic things like driving or using my laptop feel impossible some days.

i’ve read about something called post-viral fatigue and pem (post-exertional malaise) and it really sounds like what i’m dealing with. i can feel ok for a bit but then if i do even a small thing like feed my cats or go outside i crash hard after. i have to lie down and my brain just stops functioning.

i’m not sure if it’s connected to undiagnosed adhd or hormonal stuff too. i’ve had some depression before but this feels more physical than emotional. i’m waiting on blood tests but doctors don’t always take it seriously so i just wanted to know if anyone else has gone through this and if anything helped.

i have a holiday coming up and i’m scared it’s going to make me worse but i also really need the break. any advice or reassurance would be appreciated
