Am I Being Hypersensitive?

Something recently happened to me which I feel like broke my very soul into itty-bitty pieces. Like, Humpty Dumpty pieces. T's response? Accept reality and move on. Is that not a fancy way of saying "Just get over it!"? Which I know we all love to hear.

I would tell T your reaction to his/her response. I had something in the past with T where I just wanted her to understand how I was feeling about something, and she actually said to me, "I know you want validation right now, but I'm not going to give it to you." She was trying to challenge me, I think, but it wasn't what I needed right then. I was very upset about it and ended up telling her that the next session. She admitted she'd made a mistake in her approach at the time, and our relationship improved from there. So definitely say something.

Oh my, I am so sorry. I definitely know what that's like. Sometimes, like LonesomeTonight said, our T doesn't see things the way we do, and their approach isn't the most helpful. (s)he may also have not exactly realized what a big deal it was for you.
But no T in their right mind should ever downplay your feelings like that. And you should never let their response to this very real issue downplay your feelings like that. Because they don't have control over you, you do.
Definitely tell your T how his/her response effected you and what a big deal this really is to you. If (s)he still doesn't get it or seem as supportive as you'd like, don't get too discouraged. No T is perfect.

Good luck, my friend!

That's not appropriate for a therapist to say. I would definitely tell him/her next session how it made you feel.

Your therapist's responsibility is to help you overcome your struggles. Telling you to "accept reality and move on" is not helpful. It's hurtful.
