Idk what I want to do?

Basically, I’m 18 and a lot of shit happened and I’m just starting year 12. I got no idea what I want to do, initially I want to do UX/UI but I have been told that it’s a dying market. Btw, I want to plan my life for escape. The shit that had happened made me realize that I need to leave my family and not look back. Ideally, I would ask if it’s a good idea to keep with UX/UI or go into AI cuz I’m good at math and physics, plus, what abroad unis I should go?
