I think there's quite a lot of defensiveness on the thread where there needn't be, there are crap counsellors just as there are crap teachers or any other professions. Plus in a profession where the processes are very soft (talking, listening) and the outputs very intangible (people feeling better or not), it's not surprising some people have bad experiences.
Having said that, I completely disagree that friends could fulfil the same function as weekly counselling. I love my friends, which is precisely why I don't subject them to an hour of me crying, exploring, ranting, thinking aloud about the most intimate parts of my life, it would be completely beyond the bounds of our friendship. The odd phone call, upset is normal, but that regularity, plus the fact they may want to do the same and share stuff with you, means its not the same at all. If you are treating your friends like a counsellor, that's not great.
I also think sometimes you are in a place where outpouring your thoughts is extremely helpful and sometimes you are not. I saw a counsellor once for only six weeks and it was extraordinarily helpful, she was excellent and very good at getting me to think through what I was saying and stepping outside my usual perspective to view things differently, but in a very subtle way. But just getting a load of stuff off my chest and being able to be distressed, was a huge help to me.
Not all therapies work for all people, some people hate mindfulness or just don't/can't do it, doesn't mean people shouldn't offer expensive mindfulness courses.
If you don't think that the act of talking about your problems is helpful for you, and you've had repeated gos and none have worked out, I'm not sure changing therapists, or to a different type of therapy would help, because for me, just the act of blathering on is really helpful and even if they were not the world's best therapist, I would get something out of it such as emotional release.
