I used to call myself a effing moron and/or idiot all the time. I've really tried to cut that back though, and now I just tell myself stuff like, "Wow that was really stupid."
Is that an improvement? I guess... still, I wouldn't exactly say I'm very nice to myself. Not sure where I picked that up!
Do you ever call yourself terrible things in your head? Would love to hear what you guys say to yourself when you do something sub-optimal haha!
