Welcome to the Wefugees community and thank you for your question.
Your legal status is Duldung. It's not a residence title, but a suspension of deportation for a specific reason (in your case: because you started an Ausbildung).
The German state granted you a Duldung because your home country is not able or willing to provide shelter for you. By going to your home country you basically show the authorities that your life isn't in danger there anymore. That's why I don't recommend going there. You risk losing your Duldung immediately.
