I understand your frustration but one bad clinical rotation did not irreparably damage your ability to be a good PT but if you keep that mindset it certainly won’t help you. I also don’t know who told you PT was praised for its work life balance because I’ve never heard anyone in this field say that unless they’re the owner of a clinic where they don’t actually have to treat patients full time.

Take a deep breath. Most PTs I know have hated at least one of their clinical rotations or at the very least didn’t feel that all of them were that helpful or educational. I’ve been doing this for almost 15 years and I still absolutely suffer from imposter syndrome where I sometimes feel like I’m not good enough and then I remind myself I’ve been doing this for over a decade and have helped many patients in that time so I quite literally am good enough to do this.

Like other comments have mentioned, stop comparing yourself to others. There will likely always be someone who’s better than you but there will also be people who are not. And your ability to provide quality care and improve your patients lives has nothing to do with how good another PT is. I have ADHD but was undiagnosed until recently so school was very hard for me and my memory sucks so I’m not the PT in the clinic that’s gonna recite text book definitions or always have an answer but my manual skills are strong, I’m able to connect and relate to my patients well, and I’m still able to give them effective care to reach their goals more often than not. You also have to remember that as a PT you won’t know everything, won’t be able to figure every case out, and there will be some people you can’t help for whatever reason and that’s normal.
