I get you. I am not diagnosed, neither is my OH but it's possible we are given that how you describe yourself is a bit like us.
We have had a DPP, cannot be trusted with CCs (50k in 2 years!). Its lots of little things, and we can cope when its just ourselves we are looking after, but as a family unit its actually worse I think.
I cant live in mess....every one else is messy - so then I shut down its a whole cycle.
My eldest has been diagnosed ADD - though she is on meds they do FA. SHe is ramping up to exams and I can see the binge eating kicking in - she had 3 dinners the other day, then got really shitty when I questioned why, after having a steak bake, a big bowl of porridge, did she then want a MacDonalds meal! She has put on 10kg since xmas. She is also useless with money, despite us trying to explain to her about saving - she just wants to buy every new trend. I actually am beginning to think that there will need to be something in place when she reaches 18 to stop her applying for credit - but she wants to study Law so if we do that it will affect that.
Youngest the SEN teacher says is glaring ASD. Neither can stick to schedules, rules etc. I try and try and try until I honestly feel like driving into a wall at speed.
I actually had to scratch that itch and reversed into my own fence yesterday whilst screaming (we live rural so no one else saw).
My best friends both have ADHD though. One is SUPER organized, on the go, full of (nervous)energy . The other is always on the verge of a breakdown. I don't feel I can speak to them about what's going on with me as I think they will assume I am copying them, and also, I don't want to give them something else in their brain they don't need to be worrying about (if that makes sense!).
Its depressing AF. Especially when you also feel like your just being whiney, or a fraud mentioning issues. People do assume that because you are presentable your fine, its all fine, when really your going back to your dumpster fire of a car, to go to your literal shit tip of a house. But you don't seek help because to do so makes you a burden - like I already have an autoimmune condition, and a connective tissue disorder, so I feel like I would be taking the piss out the NHS to ask for any more help.
There might be a discord (cos we all know who loves a discord!) for adhd??
