It depends. If you're in a serious rut I seriously think a therapist could make it worse. You need the right fit who your brain is not going to dismiss the moment they open their mouth.
What you're illustrating there is a self-perpetuating problem: the therapist I pick might not good, so I shouldn't talk to a therapist.
Starting to talk to someone is key; that gets the process rolling. Asking for help is the start, and after doing that if one doesn't get a satisfying answer, they can ask someone else. But if they never take that first step and try to ask, they've gone nowhere.
