It wasn't my therapist, but someone else connected to my care said to me (the first time I ever met him, btw) "Are you using X-person as an excuse not to get on with your life?".

I thought it was harsh since this person didn't know me at all. It's one thing to say that to someone who you know and understand their life story. It's another thing to say that to someone who is reaching out for help for the first time.
