I can believe it had a big affect on you; I think that's perfectly reasonable! I hope you will talk to your T about it more. It's T's job to steer the conversations towards things you're working on, but it's your job to bring up topics you need to discuss, and be willing to discuss them. If it's hard for you to bring up, you could write it down, and give T the note, or you can print out this thread and take it with you.
