Our society doesn't offer many places for people to feel safe truly opening up emotionally. It can take people a very long time, and sometimes it takes 5 sessions just to build up enough trust to start to scratch the surface of whats really going wrong. I wish your comment was empathetic towards things like that, but instead it feels dismissive, and I'd worry it makes people second guess going to therapy, or starting.
Most therapists can help anyone. The right one for you can be life changing. Don't give up finding one, even if your first, second or third don't get you as far as you need to go. It probably took decades to get you to where you are, don't quit after a few weeks trying to work on it.
So... don’t be afraid to fire your therapist if it isn’t working. Trust your gut.
