Is it normal to leave work brain dead everyday when in IT?

Network Admin here. Kind of a silly post, kinda not.

Ive been working in IT, mostly Networking, for 4 years now. It’s not hard to notice that it’s a very mentally taxing field. As of probably the last year maybe year and a half, I feel like I leave work everyday just completely mentally drained. I can’t focus on much after work, and by the time I get relaxed on the weekend, it’s Monday again. I don’t feel burnt out, I just feel mentally drained. Maybe that’s burn out.. idk.

Furthermore off of being mentally drained, I feel like my memory outside of work is non-existent. I catch myself asking my S/O questions about our schedule, plans, etc multiple times because I can never remember them. I don’t remember my memory being this bad before and have definitely never been this mentally taxed consistently.

My question is, does anyone else in IT/Networking feel like their brain doesn’t work after business hours or that their memory is very poor due to the mentally taxing field IT is? Curious if I’m the only one here, and if not, if anyone has ways they manage this?

Thanks for reading and sorry for the not-super-technical post
