There's a fine line... sometimes I read the "don't worry, they won't be mad" type responses to other posters and find them reasonable and reassuring. Then again, sometimes I read the "a therapist would never do that" responses and find them arrogant and even misleading....

I think for me it depends on how well I know the person and how typical or atypical the situation is.

I mean, I'd feel reassured to see someone write that feeling angry and telling the therapist was acceptable, and upset to see someone write that a therapist would never, I dunno, yell at a client or something else that I know for a fact could happen.

P.S. I just saw your addition- I agree that having a therapist try to guarantee anything about my life is inappropriate and unhelpful. I like generic reassurances sometimes like 'it'll be alright' just as a comforting phrase, but I definitely don't trust a therapist to predict my future! No one's better equipped than me to determine how things might play out in my family. However, I do sometimes find it helpful to work on my being less anxious about potential outcomes so I don't fuel my fears of things going badly, I suppose just the difference between thinking calmly about something vs. being in a panic. My T helps w/the panic sometimes.
