You're also an R1 so everything is hard and new right now. I think many/most of us felt this way, rads has an enormous learning curve and it can be mentally draining to have to learn so much that you didn't learn in medical school. You will get better with time and experience. You can find jobs that suit your style more, if you prefer a slower pace or a more social setting, teaching, procedures etc. You seem to be stuck in this mindset that PP is the only option, but it's really not and there is a lot of variety in terms of what type of PP you want.
In regards to personalities, this is institutionally dependent but grass isn't always greener. In any field you will have in your face jerks, passive aggressive people, and just unpleasant/lazy/boring people that you have to deal with. In many other fields, these are patients that you can't really get around interacting with.
There are pros and cons to every field. You have to figure out what works best for your personality and future goals. I knew some really smart people who did family med and they got done in 3 years, get to work 30 hrs/week, sometimes telehealth visits, build relationships with their patients and feel good about what they do. On the flip side they are always nervous about the PA/NP creep, they have so much in terms of notes/social work/documentation, have to deal with difficult problem patients and dumps, and they don't really make great money relative to specialists. My surgical colleagues get to feel like the big boss and do very meaningful work but they get destroyed during residency with the workload and malignant personalities, their lifestyle for the most part is worse than mine, and the damage to their bodies and souls in that kind of training also has its costs. Working part time or limited hours as a surgeon is difficult early in training and tele-surgery doesn't exist (yet).
There's no perfect gig. Radiology is not perfect - but for some people it is much better than the alternatives.
