I really need help here because DH has been telling me for years I have to stop doing this but I haven't and now he says he's had enough.
I have a huge character flaw which is I that I am very impatient and prone to snapping when I am stressed, or tired, or hungry, or feeling guilty, or trying to do something and get interrupted, or anything at all really. So, quite often. I have a very sharp tongue and I know my tone is bad when I speak to him like that and I hate that I'm like this but it just happens before I'm aware of it. I feel like I can't change it, because it's just a crappy part of my personality. When he pulls me up on it I do make an effort and then things slip as soon as I feel annoyed with him.
I'm just going to summarise the situation as succinctly as I can for context.
I am an overachieving daughter of a perfectionist mother and I'm aware that some of the problem is linked to my own upbringing - in which we were shouted at often for things and there was a lot of stress in general - and I get very impatient and irritable quite easily (at home that is. At work I am known for being very calm, ironically, though work is stressful).
We have a nearly 2yo DD and I've just been made redundant. Money is ok but DH is freelance so even though we've always split things equally I did rely on my job to bring the stable income. I loved my job and I have no idea what I'll do next.
For the past 2 years my MIL has been deteriorating, with crises and periodic hospital stays. She lives in another country so this is very hard on my husband and we've been there as much as we can pandemic and work allowing. I really hate it there but I go for long stays to support my husband. He has been grieving during all of this and I would say became quite depressed last year. I found it very hard to manage as I felt I was keeping everything afloat. He hardly earned any money and I felt I had to keep everything going for DD.
A few other bad things happened but those are the main things. However my snapping predates all this stuff. It's often when he gets in my personal space or asks me something for the 3rd time when I'm trying to concentrate on something. I am often the one to organise everything (bills, DIY, garden, etc.) but he does do a lot at home including all the cooking and is generally very proactive. He is really a kind and loving person and a wonderful dad to DD.
I wish I could learn to be less irritable and snappy. Has anyone had this experience and been able to overcome it? AIBU for just wanting someone to tell me how the hell to change my personality? For what it's worth I am never snappy with DD or anyone else really, only DH.
