I will throw a different perspective out there and say that I DO think there is something wrong with being a PA, at least the way the OP is going about it. It was also wrong of his school to offer him this opportunity. I think he should have chosen to be a physician instead.
Midlevel degrees were very specifically designed to draw upon the experience of their students. For the NP programs this meant floor and ICU nurses, for the PA programs that meant military Medics/Corpsmen and experienced Paramedics. Half of medical school and all of residency is really just seeing, reading, and rounding on one case after another. These were men and women had been doing that, patient after patient, for a decade or more. The theory, which I agree with, was that it shouldn't take 7 years to turn someone with that kind of experience into something equivalent to a physician. The midlevels I know who came up this way, particularly the ones with extensive ICU nursing experience or former independent duty corpsmen, often were indistinguishable from physicians in the quality of their care.
In just the last decade, though, both PA and NP programs (with the exception of CRNA programs) have increasingly shifted their focus towards fresh college grads who have no real world experience. That's not a midlevel in the sense the degrees were designed for, that's just a third year medical student who has decided that he is ready to take life and death responsibility for his patients with no further training. Its unethical. Also my experience with grads of these programs has been almost completely negative.
Now I don't think this pathway to being a midlevel should exist at all, but the OP is in it now and obviously just turning back isn't really possible. My advice to the OP would be, upon graduation, to try and simulate a medical school/residency experience as closely as possible. I would recommend a PA residency, and at least 3 years working on an inpatient team (wards and/or ICU) when you are directly supervised by a physician who rounds with you and reads your note. Those positions do exist, especially I large tertiary medical centers. Read every day and, if you can work in a academic hospital, go to didactics with the residents. If you ultimately switch to more independent practice, only practice in a field where you've had a chance to see a lot of pathology with real supervision (i.e. if you did all adult inpatient don't suddenly start covering kids outpatient).
There are lots of effectively unsupervised ER, urgent care, and even inpatient positions out there for a new grad. Don't take them, at least not at first. You need to get the experience after PA school that you should have gotten before it. You owe it to your patients. And to your conscience.
