I’m not sure if this is even that unusual, but it feels like it is. 

I have been diagnosed with generalized anxiety disorder and depression. On meds for both. 

I have always struggled with this but it has been worse lately. Any time I’m in a situation where I’ve done something I regret - whether it’s my fault or not - I am completely consumed by the regret. Like, absolutely unable to let it go. It actually makes me nauseous when I think about the regretful thing enough. It happens with big/important things, and meaningless things. 

Recently I wasn’t able to find something I thought for sure I still had. It was a pretty unimportant item but I wanted it because someone told me it might be worth money. Then I realized I may have threw it out when I moved. Not a big deal at all, but it kept me up at night, and one morning even woke me up from a sound sleep. I was jolted awake and the first thing in my head was “I can’t believe I threw that away. Why would I do that? So irresponsible. Or did I really throw it out??” and then I couldn’t go back to sleep, it just took over. 

Tonight I had a realization about a bigger issue, something related to my job situation. I realized I could have been in a better situation if I hadn’t made a certain decision I made, even though at the time, it was the only thing I could have done and there was no way I could have known about this new bit of info I now know. 
Now here I am, nauseous, consumed by thinking IF ONLY I would have just ____, things would be so much better. 

I’m harping on stuff for way too long and with way too much intensity. I don’t have the ability to just say “well, it is what it is” and accept that whatever happened, happened.
