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.
I cannot recommend mindfulness enough, as already suggested by many others in this thread.
I think, you said you are already in therapy? In this case, I would definitely talk with your therapist about this and things you want to adopt beforehand. If you want a simple concrete tip, you could try the “mindfulness coach” by the US department of veteran affairs. I liked it a lot and the apps from there get good privacy recommendations from mozilla.
I am a bit suprised by the many people recommending to just stop giving fucks. Is this what you really want? Or do you just want avoid the emotions of taking control?
