You do not need to feel sorry at all, I understand completely, I've done it too! When I finished High School (that go from 14 to 19 year old here) I had a mental break down. It has been so stressful, the studies and all (I went in a classical high school, I don't know if there is a similar thing other countries, it's a high rank school were they teach you Latin, ancient Greek, philosophy, history, italian literature and very little of mathematics, arts, physic and such) that the only thought of get back to learning made me sick, I was having panic attacks and nausea. I was a total wreck, so, with my mom's approval, I took a gap year where I worked and made up my mind if I wanted to continue the studies or not. At the end, I choose a university that I liked and everything has got into place ^^ You're not alone sweety
If you want some chit-chat I'm always at your service!
