Working fully from home with your partner is not something to be taken for granted, it's very taxing for everyone concerned. You can become utterly dependent on each other for all your social interactions. Not having outlets to talk to other people is a bad situation.
I feel like I've only in the last few months got to a setup that works for me, and my partner is only working from home half the time.
You need to have honest conversations. My partner is ADHD, and I'm autistic. She'll sometimes come in and just start going off on one about the latest idea that's rooted in her head, while I'm in the middle of concentrating on work. For a while I just tolerated this and just got silently irritated, but having had a conversation about it, I just say, sorry, I'm concentrating right now, I can't just switch context like this.
Same as I can't just log off from work and then have a conversation about what we're doing at the weekend, I need time to decompress and let my brain unwind....so I strictly go out and do some exercise every day immediately after finishing work, climbing, gym, swim, whatever. Then when I get back home I'm done with my work day.
Having separate hobbies isn't a bad thing, as long as you do make sure you have some quality time with each other, and that doesn't mean a few hours in front of the TV when you're both knackered after work.
I'd also look at unplugging a bit. Not trying to be harsh here mate but your anxiety is visible on these forums, your posts are like a spectator doomscroll sometimes, you can see the dark thoughts and anxiety floating around behind the text. Which online interactions bring you joy? Which ones make you anxious?
In the last week I've decided to just disconnect myself from the news, and anything online that causes me to get into any kind of mental state I don't like. As a kinda habitual current-affairs follower my whole life, it's been quite weird, but I feel better for it. I haven't seen or heard the news for a week, so SC, no politics. I just check the sports news and the coffee/music/tech pages and let all the frankly insane **** going on in the world that I can't do anything about (other than vote) get blocked out and enjoy the blissful ignorance. Highly recommended.
This is a really interesting perspective. Because you are mostly my partner and I am yours. So it's nice to have this perspective spelled out.
Especially the randomness. This is me through and through. I will change my mind and not even realise it. Change topic etc etc.
I've also started to disconnect. To start with social media. I like taking pics and the underlying pressure to process + upload has been a stress. I obviously don't make any cash from it. So why did I let it overpower me? Before I did less and it was OK. Now, when I'm doing stuff multiple days... Do I or anyone else want pic updates? No. Primarily they are for me anyway. I like to see memories of 1 year ago today. Or just scroll back through my pictures and remember all fun stuff I've done.
This is already starting to save me time and stress.
