@deerison and @Unicornocopia, the things you list resonate so much with me. I am a chronic procrastinator in all areas of my life. I will develop a block over things and just not do them until they reach crisis point and I do this even though I know the problems I am creating.
Christmas is a bit of a nightmare for me too, as I start with all these wonderful plans to make it all magical and pinterest/Nigella-style and then end up having to pare everything back to the bare bones as I have left it all too late.
The elves get moved once every three days if I'm lucky, and never do anything creative.
Work-wise, I am a shocking doodler and also struggle to concentrate in zoom meetings. As I often chair them, this is not ideal and I often remember nothing of what anyone else has said.
I am terrified of public speaking, yet instead of dealing with that by preparing early, I always leave it until the last minute, ensuring I only just about know what I'm talking about, and often get confused and have to skip bits (I am sure nobody ever knows what I have been talking about but are just too polite to say so).
I am a hoarder too, so the house is a constant disaster and source of much angst and conflict (and I feel terrible for the kids so make endless promises to myself to sort it out, work really hard on it for a while and then lose my impetus).
I am also overweight and don't exercise enough, a bit of a disaster area generally when I list it all out.
My mental health generally is surprisingly OK though (I think) and somehow I have managed to hold down a good job, though I had to move into a role that could accommodate my inability to focus on one thing for a long time, and tendency to only do things just before the deadline.
I did an online quiz once and I matched many of the symptoms of ADHD, though not all to be fair. I did go to the doctor just before Covid but she said I needed to start taking my thyroxine medication regularly to rule out problems there, and I keep forgetting it, so have got no further (so in fairness I may not have ADD at all, just a thyroid imbalance (I definitely don't have H)).
Anyway, it is reassuring to read of others with similar issues, as I am constantly amazed at how easily other people I know manage their work and home lives.
