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.
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.
