Hi Sasha, I’ve been to art school, I graduated about eight years ago. My school is no longer around, so I can’t recommend it lol. This is what I wished I had done. I would recommend looking at what career you would like to have before picking a school. There are some illustration business classes here on svs and they go over some possible careers. Once you have an idea of where you want to end up in your career, I’d look to at what schools offer that and work backwards. Online does seem like a really good option now, svs for example has a lot of what I learned in college. I would also highly highly recommend not going into debt for this. It’s incredibly difficult to monetize creativity and having $100k+ in debt is going to make it harder. I still have around 2/3 of my student loan debt and my day job (that I have to keep to pay this debt) while based on skills I learned in school, it doesn’t really use my degree. Having no debt will give you way more freedom 
That’s some of the negative side. Art school was also a ton of fun, I learned a lot, and I did like having classes in person. I hope this gives you some ideas. While there are a lot of stresses, it can also be super fulfilling and rewarding.
