There is nothing wrong with losing your job; Steve Jobs lost his job once. Many other successful billionaires, we all share a piece of the failure cake.
My advice is:
1- Get your hands dirty in some sort of business, but don't waste all your savings.
2- Get into the market, talk to people and do some market studies, look for a niche in the market, try to start in a small jurisdiction and keep notes of everything.
3- Learn about all aspects of business, as I said before, law, finance and management. Some marketing skills, and work on your social skills.
4- Get some entrepreneurs friends, online and better in real life.
Cool, I will just simply tell you my opinion, in the end it is you who should make the decision, for me school is for people who don't have imagination and courage to learn by themselves. But in early age and with lack of experience it is easy to get carried away and take the wrong direction.
If you already found your passion and you are sure that whatever is it, it is what you want to do for next few years of your life. Take the 6 months off and go explore in that direction and see what you get. Otherwise if you are not sure yet, stay in school and try to find what you like to do, you still have long way and if the next 6 months are not them, be patient sooner or later you will find what you like to do. Then everything is going to be clear.
Explore and try to meet people and talk to them whether in school or off school.
The question is do you feel you are ready to start your own business or is it just the fact you lost your job.
My advice to you, having the idea of starting your own business is great and I encourage to do this if not now maybe later, the feeling of satisfaction of doing something you are passionate about is unlimited and will always drive you to do more.
Starting business is not only about knowing what you want to do or how to do it , there is many factors you need to know before you start your own business, like business itself, law, finance and management.
Look for a good job in the same domain you want to start your business in and start planning your business accordingly, and try to get involved in everything required from you to succeed.
