I've been angry with my T MANY times, although I've only actually told her about 5% of the time when I'm angry. I don't recommend bottling it up, no matter how big or small the anger is. I have found that, without you even knowing it, anger can affect your progress and focus in therapy... also, when I bottle up, it all comes spilling out later on, which then becomes way too much to work through at one time with my T.

Are you allowed to email your T? If so, I would send an email saying you were hurt by X. You can decide how vulnerable you want to be in the email. Your T should then be able to drive the conversation the next time you meet, if you're too nervous to bring it up on your own.

I find myself sugarcoating how angry I am when I see my T in person, whereas in email I can really let her have it When we're in person, she always says "you can scream at me, I can take it" but I never do

Good luck!
