I feel ashamed to admit this in public, but...me too. The barrier to entry is so much lower than therapy, I feel less anxiety about explaining my situation correctly, and I can quickly start over with a "new therapist" whenever I want.
Is it a replacement? No, of course not. But boy if it isn't a big help.
The only issue is that it needs a good user. Just as you can work your way into good insights, you can work yourself into bad insights just as easily. Sometimes chatgpt doesn't challenge you enough unless you ask it to under specific frameworks or paradigms. It is definitely a useful tool though.
Edit: These are all problems with real therapy too though, on further reflection. It took some time to find the therapist that works well with you. That can be a form of similar bias.
I find myself being exceptionally careful when asking questions. ChatGPT is known to lean sycophantic - biased toward agreement. And rather than asking, "Is this ...?" or "Am I ...?", I'm careful to choose prompts like, "Evaluate, or analyze...".
My hope is that this results in less sycophantic responses, but overall it's a difficult thing to measure.
