I am really struggling with my personality, disorganised nature and general memory "issues" and I'm starting to wonder if there's actually something wrong with me.
I have all these great ideas and intentions but I never get round to doing anything. I made a list of activities to do one a day in December and we haven't done any of them yet :( Either I've forgotten totally or I've remembered but been too tired or thought about it and then forgotten moments later. Or I've thought about it and then thought "What's the point? We've missed half of them." I do it with parenting situations as well, like I know how I want to deal with some behaviour of DS's but then when it happens I end up shouting and feel bad, and then of course I have the "perfect example" all worked out in my head ready to beat myself up with.
DP has conversations with me four or five times but I react like (and genuinely feel) it's the first time we've discussed that thing. (I very, very much doubt he's gaslighting me, BTW!) He gets frustrated about it. I also have a problem that I will forget I've made a decision, especially if I change my mind, for example, I think "My train ticket's about to run out, I must buy a new monthly pass" and then realise it's only a week until I'm on holiday so it would be better to buy a weekly one instead. Then by the time I'm at the station I forget I've decided this and buy the monthly one and am then annoyed that I've wasted the money. I can remember stuff from months or years ago in minute detail, though. In fact most of my memories are extremely detailed, yet I can't remember a conversation that I supposedly had yesterday or where I put my keys when I came into the house.
Several times a day on my days off from work I feel paralysed in a total panic wondering whether I've forgotten that I was actually working that day (I have actually done this when I worked in a place where my hours changed week to week). I wake up in the night afraid that I've forgotten to set my alarm or I've set it for the wrong time (I've done this too). I have totally forgotten arrangements with friends and/or remembered them last-minute, although mostly I don't bother making them because the thought of doing so is too exhausting, which is obviously affecting my social life. I've had diaries, calendars, apps, to-do lists but I forget to look at them! 
If I set an alarm I tend to ignore it.
I feel like being in my brain is like swimming through treacle most of the time. I end up doing something really addictive to avoid it, currently it's internet, but in the past I've blocked myself from internet and it's just transferred to shit TV, phone games, reading books, or in the absence of anything at all, I will just fall asleep at every given opportunity.
It's really getting me down! It's not normal, is it?!
