I'm currently going through the admissions process with grad programs, and would really like advice if anyone has the time. There's three schools that have been interested in me so far:

School A has fully admitted me to their program and graduate school with a TA position with full funding. This was a top 3 choice for me.

School B sent an email saying that I seem like a good fit for their program and would like me to visit their campus in a few weeks. Not a formal acceptance, but sounds like one might be coming. This was originally my top choice school.

School C reached out and said they will be sending a formal acceptance letter this week. Their program seems well structured and the faculty member I met was very friendly.

On paper, school C is the highest ranked of the three, followed by A, and then closely B. However, based on location preferences I'm strongly leaning away from C since it's on the opposite side of the country and I'd prefer to stay within driving distance of my parents, which is possible with both A and B.

Since looking more into A, I believe that they are the best fit overall, and my recommendation letter writers basically said that all three are great choices and I couldn't go wrong with any of them. I'm a bit worried about fully commiting before visiting though. I'd like to at least see both B and A before deciding.

I'm still not "officially" admitted to B, so I'm worried about turning down C right away. Is this unfair? I'd hate for someone else to miss a spot at C because I was waiting to hear back from B.

I'm honestly starting to get stressed by this decision. My gut feeling is that A is the school for me, but its hard to fully commit to that before I've visited the campus or even seen B / C either. I also feel guilty even being stressed by this decision- several of my friends haven't gotten acceptances yet and are just hoping to hear from at least one school. Sorry for the long rant-y post, I appreciate any input you all have.
