Ugh. But it wasn't impulsive behavior! People can't go into emergency mode (and shouldn't put you into emergency mode) over every little thing. That's counterproductive.

I bet if you'd said you wanted to get your ears pierced, it wouldn't have been as big a deal.

I think your doctor's main concern though, might have been how you reacted to her about what your friend said. Because you got so mad at it, it could be a sign of agitation. That might be where your doctor is coming from, and maybe she's retroactively labeling it as impulsive thinking because of that.

How did you react to your friend when he said he thinks you're leaving your depression and going into mania?
