I've seen 10. They're pretty useless. They promise healing and fail every time. But maybe I've just been unlucky.
The numbers show that therapy does work. That much is simply a fact, numbers are more reliable than anecdotes. But the numbers are never 100% of people either. Some people and some disorders are very treatment resistant. And it also depends on finding a good therapist, a good client-therapist relationship, a cooperative client, a good method, the right method for you, etc. Tbere are a lot of variables that matter and can make a difference.
Anecdotally I also know and have talked to many people who have been helped a lot by therapy. If you count snecdotes as more important.
Depending on how you count I've been to 4.
First one was pretty useless. Not an effective method and didn't fit me.
Second one was helping but ended up changing careers so I had to quit.
Third one didn't help me much. Wrong method that didn't fit me.
Fourth and current one has been very effective. When I first went to her I couldn't even leave my house or do exams. A year later I was going to class consistently, doing groceries, going to exams and even found a girlfriend. She also helped me through several depressions.
That being said, while she's good she's also gotten too expensive for me to go to as much as I neex anymore. On top of that my current depression is far worse than previous ones. She's a good therapist but not a magician. I don't think she can help me anymore, I think it has gotten too bad.
Anyway, you may have been unlucky in the therapists you came across. Maybe you found shitty ones (there certainly are plenty of those too) and the methods they used didn't fit you. You may have a very treatment resistant problem or you may be one of those people who doesn't reapond well to treatment, they seem to exist too. Idk which it is in your case, you'd know that better, probably. But I would encourage everyone to not ignore the actual numbers (and testimonies) which show that therapy does work for many people and many problems. And to people in general, if your current psychologist isn't working for you, don't be afraid to try a different psychologist with a different method. Cuz there are MANY very different treatment methods out there. And it can take a while before you find what works for you.
