I am a dissertation coach but I work with clients during all stages of the Ph.D. program. I would say that in my experience, those who struggle with their commitment to the Ph.D. so early on generally do find it harder to make it to the finish line. The best advice I could give you is to get as clear as you can about what you really want, in both the short and long term. If the Ph.D. path is not for you, there is nothing wrong with simply redirecting and pursuing other options. And if you do decide to stay, I would suggest you find something that will be motivating enough to get you through. That can look different for different people, it may even be something as basic as just getting what you came for. Just be clear about what is motivating you, so that you don't end up wondering whether you did the "right" thing.
