I don't understand why talking about unhelpful comments from your therapist/family members/friends/librarian is inherently wrong either.
Some days I come to psychcentral and I am feeling stressed and I cannot read or reply to certain threads because I cannot input any more stress. Other days I feel differently. I cannot say that another member should or should not participate or read this thread. That is personal decision. If it bothers them do not read it just as I don't read some threads on some days.
I am not attacking anybody, I cannot even remember who posted some things, I am just expressing my thoughts.
I have trouble reading posts in the self injury forum. So I seldom read or post there. That is me.
I think it is healthy to be able to identify when a therapist is not helpful. Independent thinking is healthy and perhaps a therapist has mispoken or we or they have misunderstood something, maybe something that can be fixed by improved communication. If that does not help then perhaps a different therapist is a good choice. That is what ultimately happened in my circumstance. I tried talking to the therapist, didn't work, talked to my Pdoc and the unit manager, didn't work. So I asked to be assigned to the other groups with the other two therapist in the program.
