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.
in my experience, the sooner you accept that life is terrible and full of pain and misery, the sooner you cease to be surprised by it being terrible and full of pain and misery.
tl;dr "this might as well happen, I guess"
You know, it's sad but I think lowering my expectations out of life really does help get through a bit. You end up a bit cynical by default, but when good things do happen they stand out more. Sure my life kinda sucks but taking it out on others does nobody any favors. Patience and kindness might come back around - but again, don't expect it.
