Smell memories are HUGE and hard to address for me. My T mentioned something one time about something ... cannot remember what exactly, but he mentioned something about the way my mother smelled. I am not at all a shouter, and I am generally VERY contained, but I freaked out. I blurted out, "NO. STOP," in what was likely a shout. He froze, I froze, and then just sat there, trying not to scream and shriek. [I'm also not a shrieker, if you hadn't guessed.] I could not speak at all, and had to keep swallowing to keep from screaming or throwing up. If I had actually smelled something that really smelled like her, I do not know if I could have held it together. Please do not feel badly about not being in control of this.

And I agree with feralkittymom that your T should request the other T to not wear the cologne, or routinely meet with you in a different room so that you are not confronted by that smell until you have time to work through it.
