Hi guys i need serious advice,

I am 26 years old and I was working as a chef in a Michelin restaurant, but I left because I worked 70 hours a week and did not receive extra payment. I've only been living in London for 3 months. The kitchen is starting to tire me out and I no longer have the enthusiasm. I want to change industries and learn new things. Many fields such as IT field, 3D modeling, digital marketing and UX designer interest me. Are there bootcamp for these in England? I'm undecided about choosing a new profession, but I want to change the sector before I get older.
