Firstly @Tails1974 welcome to the forums. It’s great to have you here.
and what you’ve described makes perfect sense. I have a love-hate relationship to this time of year. It always seems to make everyone so stressed to get it “right” and that just makes me anxious. And I hate NYE - not so much the fireworks for me - I just hate looking back at the year and feeling like it’s been another crappy year.
I think we all feel like strangers sometimes, but when it’s a time when we are “supposed to” feel connected it really does hit home.
Im sure some of the others have more tips, but for me I put some good boundaries in to make sure I get some alone time. I’m a parkrun groupie so I like to find a local parkrun that’s doing Christmas Day and New Years Day runs and commit to those. Then I know I have that locked in - and no one else in my family wants to get up and run first thing in the morning - especially at Xmas and NY.
I also choose not to drink, other than some bubbles to toast - alcohol just makes my stress worse and I can’t escape by driving somewhere if I’m over the limit.
For shopping I usually pick one shop to get everything from for gifts - usually a bookshop - then I get them all in one trip and I’m done. Food can be bought online. And even last minute gifts - Amazon do fast delivery in an emergency. Or maybe there’s a mate you can pair up with to go together - first thing in the morning is a great time in the shops - especially before school hols start.
And when you do get overwhelmed - there are some great quick actions to provide immediate release - breathing exercises, grounding by focusing on bringing yourself into the moment or distraction - I personally recite the American states in my head in alphabetical order but it can be anything. There are some tools on the open arms website to help with these https://www.openarms.gov.au/get-support/self-help-tools/show-all-tools
