At the end of the day, real life experience carries more weight than training in 80% of the theatre (unless you're a technician. If you want to be a Lighting Electrician, please get proper training). If you gut is saying don't go back, that is a very important thing to recognize. The US puts a lot of pressure on young adults to immediately know what they want to do, and to put a huge amount of money on the line to train for it - if you aren't sure, don't fork over the money. Since you said you have supportive parents, see if you can figure out some sort of an agreement with them to allow you to figure it out.
If you're interested in just about anything but performing, send a message to any local community theatres once the world has reopened and ask to talk to someone in one of the fields you're interested in. I have known of plenty of people who have sat in the corner and watched a local stage manager call a show as a way of investigating if that was something they wanted to do for themselves.
BFA degrees are a relatively new concept - while you can't really shadow performance in the same way you can other jobs in the theatre, take heart in the knowledge that the whole idea of a degree in musical theatre didn't really catch on until the late 90's, and even then it was a slow grow until the explosion around '05. Many generations of performers have gotten training outside of the college system, and you can investigate those career paths without forking over 70,000 to decide if it is the right path for you.
