@mildlymiffed Hi. I have all my budgets set up on spreadsheets, including what I need to put away every month for things like Xmas and MOTs etc.
Other paperwork I shove in a box file and file it away at the end of the year. So one file per year. All stuff like birth certificates in a separate file. And then downstairs I have a file with 12 sections. If I have an appointment in March, I put the letter in that months holder, along with prewritten and stamped birthday cards to be sent that month (I do them all in January for the year as I am a lazy cow).
Not that organised but works for me. So much stuff still needs to be kept as hard copies so that's how I do it.
@Elizaeliza Welcome! Oof that sounds like a stressful year. On the downside selling your house sucks, on the upside it means you get to choose somewhere for you and you alone, with no memories to haunt you.
I can relate to the friendships changing after the split. It can be a bit lonely, but then I felt lonely being married to my ex in a much worse way. At least now there is a reason for it.
Glad you are feeling liberated 
@Taetoes Welcome! YOU sound awesome. It's a hell.of a lot to go from being part of a couple for half your life to being single. But after two months you are already finding ways to cope with the bad days, and take joy in the good ones - that's bloody impressive! 
@KitKatBox Interesting what your counsellor said about walls. I think I would be asking her how, in light of the fact you don't want a relationship, they differ from boundaries? Does it depend on whether the counsellor approves or not?
You are doing what is right for you, and that's ok 
@Misty9 and @Mildlymiffed - glad you two are getting this moving malarkey sorted. You both sound kind of invigorated after your fresh starts.
I am a fellow Luddite too - it's a bit crap but I manage. My 66 year old mum is a tech whizz so I can ask her if needs be
