Here recently it seems like everything just gets under my skin so quickly and easily. It’s not that I get mad and take it out on others, it’s just the fact that I’m constantly annoyed and stressed. Something as simple as the dogs tracking some mud through the house will just ruin my mood. I know some people who would just laugh it off and clean it up. Meanwhile I’ll get pissed that I didn’t wipe their feet and be mad the entire time I’m cleaning it up. This has nothing to do with the dogs, it just an example. Any number of seemingly insignificant things can trigger me like that. Like forgetting something at the store and having to go back. I would love to be able to go, “well that sucks” and just get over it.
This sounds like you are stressed. In the particular example you give (I am a generally even tempered person, and having trouble with irritability today) I find exercise helps. Exhausting my body calms my mind.
If it’s a situation where the irritability is telling you something, like you are stressed because you are doing too much and the rest of your family doing too little, you may need to communicate that to them, to be able to fix it.
